A new molybdenum nickel phosphate, [H(2)en](3) Na-4[Ni(H2O)(3)][H-30((Mo16O32)-O-V)Ni-14(PO4)(26)O-2(OH)(4)(H2O)(8)] center dot 8H(2)O 1, has been hydrothermally synthesized and structurally characterized. Compound 1 crystallizes in the monoclinic space group P2(1/c) with a = 18.6118(6) angstrom, b = 20.9879(6) angstrom, c = 22.9360(5) angstrom, beta = 116.678(2)degrees, V = 8005.5(4) angstrom(3) and Z = 2. The polyoxoanion of 1 exhibits an unusual divacant wheel-type cluster in which two {NiO6} octahedra are lost from the well-known "saturated" {Mo16TM16P26} wheel. The two vacant sites are occupied by two protonated ethylenediamines (H(2)en) via the strong hydrogen-bonding interactions between the surface O atoms of the polyoxoanions and the amine group derived from the H(2)en ligands. DC susceptibility measurements show that compound 1 exhibits strong antiferromagnetic interactions inside the wheel-type cluster.
