title: (η-Benzene)(2,2'-bipyridine-κN,N')chloridoruthenium(II) chloride methanol sesquisolvate.
abstract: In the title compound, [RuCl(C(6)H(6))(C(10)H(8)N(2))]Cl·1.5CH(4)O, the Ru(II) atom is in a distorted octa-hedral environment coordinated by an η(6)-benzene ring, a chelating 2,2'-bipyridine ligand and a chloride ion. The asymmetric unit is completed by a chloride anion and two methanol mol-ecules, one of which is disordered about a centre of inversion with an occupancy of 0.5. It is an example of a ruthenium complex with a less sterically congested environment than in similar derivatives. In the crystal structure, O-H⋯Cl hydrogen bonds, together with π-π stacking inter-actions [centroid-centroid distances of 3.472Å(2) Å], stabilize the structure.
