Abstract

The monomeric Ni(II) containing Wells-Dawson polyoxometalate (POM) complex K 2 Rb 6 Ni 0.33 [P 2 W 18 O 62 ]Cl 2 ~15.3H 2 O (K 2 Rb 6 -1) was synthesized by the reaction of [Ni 2 (μ-OH 2 )(O 2 CCMe 3 ) 4 (HO 2 CCMe 3 ) 4 ] and K 6 [P 2 W 18 O 62 ]. 19H 2 O in aqueous medium. The compound had been characterized by elemental analysis, FTIR, TGA and single crystal XRD (trigonal, space group R m , cell length a = 37.3660(4), b = 37.3660(4), c = 12.8340(2) Å, α = 90, β = 90, γ = 120°, V = 15518.4(3), Z = 9). Oxidation state of Ni(II) was calculated through bond valence sum (BVS). The magnetic susceptibility study showed magnetization with temperature range 5K-300K.
