Crystal Structure of cis-Bis(5-chloro-2-(phenylazo)pyridine)-dichlororuthenium(II)

Abstract

The complex [Ru(Clazpy)2Cl2] (Clazpy = 5-chloro-2-(phenylazo)pyridine) was synthesized and characterized by X-ray diffraction analysis. The geometry around ruthenium(II) was distorted octahedral with coordinating from two chloro ligands and four N-donor atoms of two Clazpy units. The chloros are cis while the N(pyridine) atoms are trans. The Ru-N(pyridine) distance (2.037(2)A) is slightly short compared to those in other ruthenium(II) complexes with azoimine ligands.
