Crystal structure of di­chlorido­[2-(1H-imidazol-2-yl-κN³)imidazolato-κN]bis­(tri-n-butyl­phosphane-κP)rhodium(III)

The Rh^III atom in the title compound shows a distorted octa­hedral coordination geometry. N—H...N hydrogen bonds involving the N atoms of the singly deprotonated biimidazolate ligands lead to the formation of inversion dimers.
