Aquachloro[tris(methylpyridyl)amine]cobalt(III) diperchlorate monohydrate

Abstract

The tris­(methyl­pyridyl)­amine (tpa, C18H18N4) ligand in the title complex, [CoCl(tpa)(H2O)](ClO4)2·H2O, is bound to the CoIII centre in a tripodal fashion through the four N-donor atoms, allowing the chloro and aqua ligands to occupy the remaining cis sites in the octahedral coordination geometry. The chloro ligand is coordinated trans to the tertiary amine N atom of the tpa ligand. A solvent water mol­ecule is hydrogen bonded to the aqua ligand. The metal–ligand bond lengths are typical for CoIII complexes.
