A series of new transition metal complexes [ML(Ln)Cl2] where Ln = L13, L15 and L17 (L(13) = 11,13-dimethyl-1,4,7,10-tetraazacyclotrideca-4,6,10,13-tetraene-5,6-diol, L(15) = 9,11-dimethyl-1,4,8,12-tetraazacyclopentadeca-1,3,8,11-tetraene-2,3-diol and L(17) = 10,12-dimethyl-1,4,9,13-tetraazacycloheptadeca-1,3,9,12-tetraene-2,3-diol) and M = Cu(II), Co(II), Ni(II), Mn(II) and Zn(II) have been synthesized by template method. All the synthesized complexes were characterized by IR, UV, ESR, X-ray microanalysis, elemental analysis, thermal studies and magnetic susceptibilities and the geometry of the complexes found to be octahedral.
