Di-μ-acetato-κ4O:O′-μ-oxido-κ2O:O′-bis[cis-(2,2′-bipyridine-κ2N,N′)-trans-(pyridine-κN)ruthenium(III)] bis(hexafluoridophosphate)

Abstract

The hemerythrin-type dinuclear title complex, [Ru2(CH3COO)2O(C10H8N2)2(C5H5N)2](PF6)2, consists of two RuIII ions with a six-coordinate octa­hedral 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 inter­actions generate a three-dimensional network in the crystal structure. π–π stacking inter­actions [centroid–centroid distance = 3.6389 (3) Å] between inversion-related 2,2′-bipyridine rings are also observed.
