Structure of mixed-anions tris(2-pyridylmethyl)amine Mn complex, TPAMn(η2-NO3)(η-ClO4)

Abstract

Mononuclear mixed-anions Mn complex of TPAMn(η2-NO 3)(η-ClO4), where TPA is tris(2-pyridylmethyl)-amine, has been synthesized and characterized. The neutral TPAMn(η2- NO3)(η-ClO4) was obtained from the reaction between Mn(NO3)2·4H2O and [H3TPA] (ClO4)3 in MeOH. X-ray crystallographic structure of mononuclear TPAMn(η2-NO3)(η-ClO4) complex showed a seven-coordinated geometry with a tripodal tetradentate TPA, a terminal perchlorate and an η2-bound nitrate.
