  Abstract:  The reaction of MgCl2.6H2O, CaCl2.6H2O, SnCl2.2H2O, VOSO4.3H2O and PtCl2 with deprotonated diclofenac, sodium {2-[(2,6 dichlorophenyl)amino] phenyl} (L) were studied in aqueous solutions. Coordination compounds of the formulae [Mg(L)2 (H2O)4].6H2O, [Ca(L)2(H2O)4].H2O, [Sn(L)2(H2O)2], [VO(L)2(H2O)2] and [Pt(L)2(H2O)2] were synthesized and characterized by elemental analyses, spectral (UV-VIS, IR) and thermal analysis. In all studied compounds, {2-[(2,6-dichlorophenyl)amino]-phenyl}acetate act as a monodentate ligand with coordinate involving the carboxylate oxygen atom. The studied compounds heated in air, lose crystallization water molecules below 423K where as that water eliminated above 423 K is considered as coordination water
