Sci. Vol. 30 (3) 2017 Introduction Metal complexes play an essential role in agriculture, pharmacy, medicine and chmical industries[1]. Complexes of salicyaldehyde were among the first systems which were studied by infrared spectroscopy[2].Simalarly dithiocarbamate metal complexes are known for their dithiocarbamate metal complexe whic are known for their various applications[3]which include vulcanization accelerators, high pressure lubricants, and active ingredients of fungicides, pecticides and pharmaceutical product.[4,5,6] This kind of compounds has been reported in literature to show detoxicant and immunophavm acological properties such as antibacterial ,antifungal etc[7] ,also they have been reported as group of useful bridging ligands for creating mixed valence poly nuclear system[8].Anextensive search through literature showed that many mixed ligand dithiocarbamate complexes with Schiff base moiety as a part of its coordination ligand have been widely reported[8]. In this work we report on the synthesis and characterization of Fe(ІІ), Co (ІІ),Ni(ІІ),Cu(ІІ),and Zn( ІІ) complexes with dithiocarbamate ligand4-aminobenzene dithiocarbamateand N-donor ligands. Experimental All reagents and solvents were of analytical grade and used as supplied from fluka or BDH chemical companies infrared spectra which were recorded on Brucker Tensor 27Co.FTIR spectrophotometer in 400-4000 cm -1 range using KBr discs: and CsI discs in the range 4000-2000 Conductivity measurements were carried out on 10 -3 M solution of the complexes in DMF using conductivity meter PCM3 Jen way at ambient temperature . The electronic spectra were recorded on ashimadzu UV-visible spectrophotometer UV-160 for 10 -3 M solution of complexes in DMF as a solvent at 25 ₒ C using 1cm quartz cell. Metal content was determined using AA670 atomic absorption .Melting point was recorded on an electro chemical 9300 apparatus and uncorrected. The magnetic measurements were carried out of the solids by faradys method using Brucker BM6 instrument. 1.1 Prepation of sodium p-phenylene diamine dithiocarbamate : The p-phenylene diamine dithiocarbamate ligand(PABdtc) was prepared by literature method [7] by adding (0.1mol,10.81g) of p-phenylene diamine dissolve in 15 cm 3 distilled water to a solution (0.1mol,4.0g) of sodium hydroxide with reflux 30 mint and continuous stirring . The resulting mixture was cooled in ice and (0.1 mol,76g) carbon disulfide was added dropwise with continous stirring .The crude product was extracted by ether, the form precipitate was filtered off , washed with ether and dried.The reaction is shown in figure(1). 2.1 Preparation of complexes [M(PABdtc)2] M= Fe(ІІ ),Co(ІІ ),Ni(ІІ ),Cu(ІІ ),Zn(ІІ ) To a solution containing (0.001 mol) of the required salt FeSO4.7H2O ,Co(NO3)2.6H2O, Ni(NO3)2.6H2O ,Cu(NO3)2.3H2O, ZnSO4.7H2O in a small amount of water/aceton 20/80 respctively was added to (0.002mol) of sodium PABdtc .The mixture was stirred for about 30 mint, then the precipitate was filtered , washed several times with acetone and finally air dried , other complexes were prepared by the same procedure. The reaction is shown in figure (2). Chemistry |132 https://doi.org/10.30526/30.3.1608 7302(عام 0العدد ) 03مجلة إبن الهيثم للعلوم الصرفة والتطبيقية المجلد Ibn Al-Haitham Jour. for Pure & Appl. Sci.

The reaction is shown in figure (5). Results and discussion The new ligand was prepared for the reaction of P-phenylenediamine with sodium hydroxide then reflux 30 mint then added carbon disulfide, the complexes were prepared through direct reaction of the metal salt, FeSO4.7H2O or Co(NO3)2.6H2O or Ni(NO3)2.6H2O or Cu(NO3)2.3H2O or ZnSO4.7H2O hydrous with the above ligand in (1:2) molar ratio. The values of conductivity in dimethyl formamide solution of the complexes range from(1.7- 16.77)Ω -1 .cm 2 .mol -1 which are typical values for non electrolyte type [9]while complexes of the type ( R)4N[Ni(PABdtc)3]are 1:1 electrolyte. Infra-red spectral studies The important IR band of ligand and its complexes are listed in table( 2). The stretching frequency of the υ (C=N) band for the dithiocarbamates was intermediate between the stretching frequencies associated with typical single and double bonded carbon and nitrogen atoms [10].The υ (C=N) and υ (C=S) were observed in the ranges of (1500-1550) cm -1 and (900-980)cm -1 . The presence of only one band in the later region reports the bidentate Chemistry |133 https://doi.org/10.30526/30.3.1608 7302(عام 0العدد ) 03مجلة إبن الهيثم للعلوم الصرفة والتطبيقية المجلد Ibn Al-Haitham Jour. for Pure & Appl. Sci. Vol. 30 (3) 2017 coordination of the dithio ligand[11] .The( N-H) band of dithiocarbamate was observed in the range ( 3319- 3455 cm -1 ) IR spectra showed a new band at (420-426)cm -1 the evidence for the coordination of metal to sulfurυ (M-S) , this behaveior may be attributed to the electron releasing of the amines , which forces hig electron density towards the sulfur atoms , the υ (M-N) was observed in the (465-523)cm-1 region [12] In the adduct ,the band corresponding to υ (N-H) of the ethylene diamine (6,14,22,32 and 40) was observed at lower frequency (3211-3270)cm -1(13) . which indicates that it was shown in coordination with metal ions , as well as the band υ (C=N) ring which was observed as (1479- 1500)cm -1 which means the coordination of the donor atoms with the metal ions[14] . Electronic spectral studies The UV-visible spectra of ligand and their complexes of 10 -3 M solution in DMF were recorder; the results were listed in table (2) . The UV-visible spectrum of the Fe( ІІ ) complex (1) gave absorption peak at (10309cm -1 ) , which correspond to 5 E→ 5 T2 transition in atetrahedral geometry [15] .complexes(2-8) shows absorption peaks at the range a(10869- 12820cm -1 ) , wich were assigned to 5 T2g→ 5 Egtransition [16] in Octahedral geometry. Figure(13). The Co( ІІ )complex( 9) exhibited an absorption peak at (16666cm -1 ) region , which was assigned 4 A2(F)→ 4 T1(P) transition [17]. In tetrahedral configuration of this complex and the absence of 4 A2(F)→ 4 T2(F) and 4 A2(F)→ 4 T1(F) , are due to the sensitivity of the instrument used. Figure (14). Complexes (10-16) show three absorption peaks at the range (9731-10394cm -1 ), (14367- 16447cm -1 , 18726- 22736cm -1 ) which were assigned to 4 T1g(F)→ 4 T2g(F), 4 T1g(F)→ 4 A2g(F) and 4 T1g(F)→ 4 T1g(p) transition in octahedral configuration [18] the Ni(ІІ ) complex (17) shows two absorption peaks at (8523cm -1 ) and (14670cm -1 ) which were assigned to 3 T1(F)→ 3 A2(F) and 3 T1(F)→ 3 T1(P) transition in atetrahedral geometry [15]respectively, the complexes (18-26) show three absorption peaks in the range (9611-10330cm -1 ), (14326- 18096), (20567-25585cm -1 ) ,which were assigned 3 A2g(F)→ 3 T2g(F), 3 A2g(F)→ 3 T1g(F)and 3 A2g(F)→ 3 T1g(p)[19]in octahedral geometry . figure (15)The Cu( ІІ ) complex(27) gave an absorption peak at (9083cm -1 ), which correspond to ( 2 T2→ 2 E) transition in a tetrahedral geometry [21]figure (16), the complexes (28-34) show abroad peaks in the region(9960- 12787cm -1 ) , which was assigned to 2 Eg→ 2 T2g transition which may be formed from the combination of three transitions 2 B1g→ 2 A1g, 2 B1g→ 2 B2g, and 2 B1g→ 2 Eg in octahedral geometry. Magnetic susceptibility measurements The magnetic moments of the complexes Table(1) were measured at (25 ₒ C). The magnetic moments for Fe (ІІ ),Co (ІІ ), Ni(ІІ) and Cu(ІІ) complexes (1,9,17,27) are (1.75- 4.95 B.M) suggesting atetrahedral geometry [15] . The low values of magnetic moments for complex(17 and 27) are due to antiferromagnetic interaction. The magnetic moments values of the other complexes (2-8,10-16,18-26,28-34) were in the range (1.65-5.13B.M) in octahedral geometry [15] Chemistry |134 https://doi.org/10.30526/30.3.1608 7302(عام 0العدد ) 03مجلة إبن الهيثم للعلوم الصرفة والتطبيقية المجلد Ibn Al-Haitham Jour. for Pure & Appl.
