The reaction of benzotriazole
carbaldehyde with 5-(4-chloro-phenyl)-[1,3,4]
thiadiazol-2-ylamine, and 5-(3-bromo-phenyl)-
[1,3,4]thiadiazol-2-ylamine resulted in the formation
of new tridentate ligands; benzotriazol-1-
ylmethylene-[5-(4-chloro-phenyl)-[1,3,4]thiadiazol-
2-yl]-amine L1 and benzotriazol-1-ylmethylene-[5-
(3-bromo-phenyl)-[1,3,4]thiadiazol-2-yl]-amine L2,
respectively.Monomeric complexes of general formulae
[M(Ln)Cl] (where;M= Co(II),Ni(II), Zn(II))
were obtained fromthe reaction of these ligandswith
Co(II), Ni(II) and Zn(II) metal ions. The mode of
bonding and overall geometry of the complexeswere
determined through IR, UV-Vis, NMR, magnetipropermoment
measurements, elemental analysis, metal
content, chloride content and conductance. The IR
data revealed that the nitrogens of the Schiff-base
and that of triazole moiety are coordinated to metal
ion, in a tridentate fashion. The physico-chemical
studies revealed the formation of four-coordinate
complexes with distorted square planar for Co(II),
and Ni(II) and five coordinate complex with Zn(II).
