Research Abstract

A series of novel dinuclear, mixed-ligand complexes having the general formula [M2(tpt)(L)4]Cl4 · nH2O where M=Ni(II), Co(II) or Cu(II); tpt = 2,4,6-tris(2-pyridyl)-1,3,5-triazine; L = dithiooxamide (dto) or thiosemicarbazide (tsc); n = 2-4, have been synthesized and characterized. The tpt molecule is flexidentate, where it can behave as di- or tridentate dinucleating ligand. The coordination mode of tpt to M(II) apparently occurs through the pyridyl and a triazine nitrogen atoms. All the mixed-ligand complexes are dinuclear with a bridging tpt molecule and having an octahedral structure. The complexes were characterized by chemical analyses, spectral, molar conductance and thermal studies.
