Crystal structure and electronic and magnetic properties of hexacyanoosmate(III)

The [OsIII(CN)6]3- anion is prepared by chemical oxidation in aqueous solution and isolated as yellow prisms of [Ph 4P]3[OsIII(CN)6]·6H 2O (1). This species crystallizes in the triclinic space group P1 with cell parameters a = 13.7609(11) Å, b = 16.2275(13) Å, c = 17.0895(14) Å, α = 91.4040(10)°, β...
