Abstract

The asymmetric unit of the title compound, [RhCl2(C10H8N2)2]ClO4, consists of one unit of the cationic complex [RhCl2(bipy)2]+ and one uncoordinated perchlorate anion. The RhIII atom is coordinated by four N atoms from two bipyridyl ligands and two Cl atoms, forming a distorted octa­hedral environment. The Cl ligands are cis. Two intramolecular C—H⋯Cl hydrogen bonds occur in the cationic complex . In the crystal, mol­ecules are linked together by a hydrogen-bond network involving the H atoms of bipyridyl rings and perchlorate anions. An O atom of the perchlorate anion is disordered over two sites, with an occupancy-factor ratio of 0.78 (3):0.22 (3).
