Crystal structure of a dinuclear ruthenium(II) complex with a bent CO(2) (2−) bridge

The mol­ecular and crystal structures of a CO(2) (2−)-bridged dinuclear ruthenium complex is reported, namely, μ-carbonito-κ(2) C:O-bis­[bis(2,2′-bi­pyridine-κ(2) N,N′)carbon­ylruthenium(II)] bis­(hexa­fluorido­phosphate)–aceto­nitrile–diethyl ether (1/1/0.5), [Ru(2)(CO)(2)(C(10)H(8)N(2))(4)(μ:κ (2)...

Sumario:The mol­ecular and crystal structures of a CO(2) (2−)-bridged dinuclear ruthenium complex is reported, namely, μ-carbonito-κ(2) C:O-bis­[bis(2,2′-bi­pyridine-κ(2) N,N′)carbon­ylruthenium(II)] bis­(hexa­fluorido­phosphate)–aceto­nitrile–diethyl ether (1/1/0.5), [Ru(2)(CO)(2)(C(10)H(8)N(2))(4)(μ:κ (2)-C:O-CO(2))](PF(6))(2)·CH(3)CN·0.5C(4)H(10)O. The complex cation in the title compound consists of two {Ru(CO)(bpy)(2)}(2+) units (bpy = 2,2′-bi­pyridine) singly bridged by a μ:κ(2)-C:O carbonite anion, resulting in an unsymmetrical dinuclear structure. Some of the inter­atomic C⋯O distances involving the carbonyl ligands are shorter than the sum of the van der Waals radii. There are intra­molecular C—H⋯O and aromatic π–π contacts in the cationic complex. In the crystal, the cations are linked by pairs of C—H⋯F hydrogen bonds in addition to weak C—H⋯F inter­actions between the solvent mol­ecules and PF(6) (−) counter-anions. The equatorial F atoms of one of the PF(6) (−) anions are disordered over two sets of sites with an occupancy ratio of 0.908 (7):0.092 (7) while the central O atom of the diethyl ether solvent mol­ecule is disordered over an inversion centre.
