Abstract
The chelating properties of 4-(p-methylphenyl)-3,5-bis(pyridin-2-yl)-1,2,4-triazole (MBPT) were investigated through the study of the crystal structures of [Co(MBPT)2(H2O)2](ClO4)2·4H2O (1), [Ni(MBPT)2(H2O)2](ClO4)2 (2) and MBPT and the analysis of IR and ESIMS spectra. The metal atom is in a distorted octahedral environment. Two bidentate chelating ligands (MBPT) coordinate to metal center equatorially and two water molecules coordinate axially. Each MBPT coordinates via one triazole nitrogen atom and one pyridine nitrogen atom. The magnetic measurements show that the complexes are high-spin species in the 75-300 K range.
