Trans-(Methanol)(methyldiphenyl- Phosphine)bis(pentane-2,4-dionato)-cobalt(III) hexafluorophosphate hydrate

Preparation of trans-(Methanol)(methyldiphenyl-phosphine)bis(pentane-2,4-dionato)-cobalt(III) hexafluorophosphatehydrate is described. There is an intermolecular hydrogen bond between the OH group of the coordinated methanol and one of the O atoms of the acac ligands in an adjacent complex cation, [giving a centrosymmetric dimeric dicationic complex. This is, to my knowledge, the first X-ray crystallographic study of a non-organometallic cobalt(III) complex bearing a methanol ligand, although two organo?cobaloxime derivatives with a coordinated methanol ligand have been reported. The population of these disordered atoms were assumed to be 0.5. The O atom of water of crystallization was treated as two partial-occupancy isotropic O atoms. H atoms bound to the O atom were not included in the calculation. All other H atoms were included in the structural calculation by means of a riding model.
