Crystal Structure of [(1,2-bis(2-pyridine-2-carboxamido)-4,5-dimethylbenzene) (dipyridine)]cobalt(III) Perchlorate

Abstract

The structure of Co(III) complex containing a tetradentate Me₂bpb^2- ligand and two pyridne ligands was determined by the X-ray diffraction method. Four N atoms of the 1,2-bis(pyridine-2-carboxamido)-4,5-dimethylbenzene (Me₂bpb^2-) ligand and two pyridine ligands are coordinated to the Co(III) atom with an N(py)-Co-N(py) angle of 175.97(19)°. The coordination geometry of the Co atom is octahedral(O_h) with six nitrogen atoms: four from a Me₂bpb^2- ligand and two from pyridine ligands.
