Abstract: This work includes two parts : 1. Synthesis and identification of some new antimony (III) complexes by thereaction of antimony trichloride with the ligands methotrexate (L1) and benzothiazole (L2) in the mole ratio of 1 : 1 and 1 : 2 ( M : L).The new compounds were characterized by means of FTIR, UV, CHNS analysis and atomic absorption, in addition to some of physical properties (color and melting point) . These analysis showed that the Sb is bonding with oxygen of carbonyl (C=O) in the amide group of the methotrexate (MTX), while with nitrogen atom of benzothiazole (BZT) . According to the data obtaind from these analysis, the suggested structure for the complexes is trigonal bipyramide (Tbp) .2. Cytotoxicity evaluation of these compounds against cancer cell line .The new compounds and the starting materials were used to evaluate their cytotoxic effect in the different concentrations of ( 10, 8, 6, 4, 2 and 1 μg/ml) for each against Hela and Rhabdomyosarcoma cell lines. The results showed thatall these compounds are highly effective in inhibition of tumor cell line growth (Hela and Rhabdomyosarcoma ) .The highest values for inhibition agains Hela and Rhabdomyosarcoma cell line were 73% and 88% in the case of Sb - benzothiazole complexes respectively. Comparing the results of the new complexes with those of the starting materials , it is very obvious that they are much higher in their effectiveness due to the synergestic effect of antimony with Methotrexate and Benzothiazole since they are themselves were effective against cancer

Two mixed ligands were chosen : sulfamethoxazole and 4,4/ - dimethyl - 2,2/ - bipyridyl (L2). This is done to prepare another series of complexes with some metal ions ( Co(II), Ni(II), Cu(II), Cd(II), Cr(III) , V(IV), Pd(II) and Au(III)) in order to investigate the coordination behavior of these ligands(L1) and (L2) toward these metal ions.These complexes, already prepared by the solid state, were characterized by the elemental analysis (C.H.N.S) and FT - IR , UV - Vis spectroscopy, in addition to the flame atomic absorption, magnetic susceptibility , melting point and conductivity measurements. According to the results obtained, it is noticed that ligand L1, with the light and heavy metal ions, clearly behaves as a bidentate through the O atom of sulfonyl group and N atom of sulfonylamid group for all the prepared complexes except Cu(II) and Ni(II). In this case, the ligand confirms that the bonding of the metal ion in a tridentate chelate through the O atom of sulfonyl group and N atom of sulfonylamid group and N atom of amine group.While L2 behaves as a bidentate ligand through two N atom. Conductivity measurements have shown that all the prepared complexes are ionic except PdL1L2 complex. Based on the results of the measurements, the following formula have been suggested for the new prepared complexes : - [VOL1L2]SO4.2H2O and [CuL1L2]2( NO3)4.0.5H2O have square pyramidal geometry while the following complexes are having octahedral geometry : - [CrL1L2 Cl2] Cl.H2O,[NiL1L2NO3]2 ( NO3)2.0.5 H2O,[PdL1L2 Cl2].0.5H2O,[PtL1Cl3H2O]Cl.H2O, [Au L1L2Cl2] Cl.2H2Oand the complexes below have tetrahedral geometry : - [CoL1L2] (NO3)2.3H2O,[CdL1L2](NO3)2.3H20 while [PdL1Cl]2 Cl2.H2O,[AuL1Cl2]Cl.3.5H2O,[RhL1ClH2O]Cl2.0.5H2O have square planar geometry.Different bonding and structural behaviors were revealed throughout the study of coordination chemistry of the newly prepared metal complexes.The nature of bonding between the metal ion and the donor atoms of the ligands were demonstrated by calculating Racah parameter and the other ligand field parameters which were calculated using suitable Tanaba - Sugano diagrams.The nature of the complexes in ethanol solution was studied for some of the prepared complexes such as (RhL1,PdL1,PtL1 and AuL1) in the solution state to determine the ratio between ligand to metal state by using the molar ratio method which gave results which approximately identical results when compared to those obtained from the isolated solid state. Besides the stability constant of the prepared complexes were studied and it was found that they were stable in molar ratio 1 : 1.
