ABSTRACT

A series of metal complexes synthesized by the reaction of Schiff bases (L1- L6) with the Cu metal acetates. The ligands used for the synthesis of metal complexes are L1(2-{[1-(2,4-dihydroxyphenyl)ethylidene]amino}-1,3-benzothiazole-6-sulfonamide), L2(2-{[1-(2-hydroxyphenyl)ethylidene]amino}-1,3-benzothiazole-6-sulfonamide), L3(2-[(1H-pyrrol-2-ylmethylidene)amino]-1,3-benzothiazole-6-sulfonamide),L4(2-[(pyridin-2-ylmethylidene) amino]-1,3-benzothiazole-6-sulfonamide), L5(2-{[1-(thiophen-2-yl) ethylidene]amino}-1,3-benzothiazole-6-sulfonamide and L6(2-[(2-hydroxy benzylidene) amino]-1,3-benzothiazole-6-sulfonamide). The data obtained was preceding using XRD data analysis program. From the experimental measurements, various parameters, Crystal System have been estimated. The XRD analysis revealed that all complexes show good intense and sharp peaks, indicating high crystallinity of complexes.
