Abstract
Two novel dinuclear clusters, [Ni(pmmat)·ClO4]2 (1) and [Co(pmmat)·ClO4]2 (2) (Hpmmat = 3,5-bis[(2-pyridyl-2-methoxyl-methyl)-amino]-1,2,4-triazole), have been constructed from a rare multidentate chelating ligand. The formation of Hpmmat ligand involves the in situ addition reaction of C=N groups and CH3OH solvents in the presence of Ni2+/Co2+ ions as Lewis-acid catalysts and coordination agents. Compounds 1 and 2 are similar structures that have a dinuclear cluster (M2) (M = Ni and Co) aggregation. Moreover, the magnetic properties of them have been also investigated.
