摘要：

The title compound, bis(tetraphenylphosphonium) mu-oxalato-O-1, O-2:O-1', O-2'-bis[aqua(oxalato-O-1, O-2)oxovanadium(IV)] octahydrate, [(C6H5)(4)P](2)[V2O2(C2O4)(3)(H2O)(2)].8H(2)O, consists of an anionic vanadyl dimer linked by an oxalate ligand and additionally coordinated by two non-bridging oxalate and two water molecules. Both the bridging and non-bridging oxalates act as bidentate chelating ligands, forming five-membered rings with the metal centres. The V-IV atoms are six-coordinated, forming a distorted octahedral geometry. A two-dimensional O-H ... O hydrogen-bonding network of water molecules and oxalate O atoms stabilizes the structure.
