fac,trans-

The crystal structure of the heterobimetallic title compound, [ReRuCl(C(10)H(16)As(2))(2)(C(10)H(8)N(2))(2)(CO)(3)](PF(6))(2). 2C(3)H(6)O, is described. Both metal centres have pseudo-octahedral coordination geometries, with a facial arrangement of the carbonyl ligands at Re(I) and a trans disposition of the diarsine ligands at Ru(II). The dihedral angle between the pyridyl rings of the 4, 4'-bipyridine bridging ligand is 13.9 (6) degrees.
