Abstract

Two new complexes, trans-[CuL2(ClO4)2] (1) and cis-[CoL2(H2O)2](ClO4)2 · 2H2O (2) with 3-(p-methoxyphenyl)-4-(p-chlorophenyl)-5-(2-pyridyl)-1,2,4-triazole (L), have been synthesized and characterized by elemental analysis, FT-IR, ESI-MS, TGA/DSC, powder XRD, and single crystal X-ray crystallography. Each L in the complexes is chelating bidentate via one N of pyridyl and one N of triazole. Both complexes have similar distorted octahedral [MN4O2] cores (M = Cu2+ and Co2+) with two in trans-positions in 1 but two H2O molecules cis in 2.
