Diaqua[N,N′-(o-phenylene)bis(pyridine-2-carboxamidato)-κ 4 N]manganese(III) perchlorate

Abstract

In the MnIII complex of the title compound, [MnIII(C18H12N4O2)(H2O)2]ClO4, the MnIII atom is coordinated by four N atoms from the bpb2− [1,2-bis(pyridine-2-carboxamido)benzene] ligand located in the equatorial plane and two O atoms of water molecules at axial positions, yielding a distorted MnN4O2 octahedral coordination geometry. The bpb2− ligand is nearly planar, with a maximum deviation of 0.2311 (3) Å from the mean plane. The MnIII complex cation and the perchlorate anion, both of which are located on twofold rotation axes, are connected by O—H...O and C—H...O hydrogen bonds into a three-dimensional supramolecular network structure.
