Abstract

We describe the synthesis of a number of 1, 3-azol-2-yl-, 1, 3-benzazol-2-yl-, and azinyl- based bis (o-azaheteroaryl) methanes (LH, L-= Het2CH-) and their coordinating properties toward divalent transition metals (Zn, Cu, Co, Ni, Hg, Pd). This extended investigation includes both symmetrical and unsymmetrical ligands based on several substituted and/or unsubstituted thiazole, benzothiazole, benzoxazole, benzimidazole, pyridine, and ...
