title: Di-μ-acetato-κ(4) O:O'-μ-oxido-κ(2) O:O'-bis-[cis-(2,2'-bipyridine-κ(2) N,N')-trans-(pyridine-κN)ruthenium(III)] bis-(hexa-fluoridophosphate).
abstract: The hemerythrin-type dinuclear title complex, [Ru2(CH3COO)2O(C10H8N2)2(C5H5N)2](PF6)2, consists of two Ru(III) ions with a six-coordinate octa-hedral geometry, bridged by an oxide and two acetate ligands, with a bidentate 2,2'-bipyridine ligand and a pyridine ligand bonding at terminal positions. The Ru-Ru distance and Ru-O-Ru angle are 3.2838 (3) Å and 121.79 (7)°, respectively, and the average Ru-N(pyridine) bond length is 2.164 (8) Å. Several C-H⋯F, C-H⋯O and C-H⋯N inter-actions generate a three-dimensional network in the crystal structure. π-π stacking inter-actions [centroid-centroid distance = 3.6389 (3) Å] between inversion-related 2,2'-bipyridine rings are also observed.
