Abstract

A new molybdenum nickel phosphate, [H2en]3Na4[Ni(H2O)3][H30(MoV16O32)Ni14(PO4)26O2 (OH)4(H2O)8]·8H2O 1, has been hydrothermally synthesized and structurally characterized. Compound 1 crystallizes in the monoclinic space groupP21/c with a = 18.6118(6) Å, b = 20.9879(6) Å, c = 22.9360(5) Å, β = 116.678(2)°, V = 8005.5(4) Å3 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 (H2en) via the strong hydrogen-bonding interactions between the surface O atoms of the polyoxoanions and the amine group derived from the H2en ligands. DC susceptibility measurements show that compound 1 exhibits strong antiferromagnetic interactions inside the wheel-type cluster.
