Two new hybrid compounds assembled from Keggin-type polyoxometalates and transition metal coordination complexes

Abstract

Two new hybrid compounds based on Keggin-type polyoxometalates: {[PMo 12O 40][Ni( Phen) 2(H 2O)] 2}·K·2OH − ( 1) and [Cd 2( Phen) 4Cl 2][HPW 12O 40]·H 2O ( 2) ( Phen=1,10-phenanthroline), have been prepared and characterized by IR, UV–vis, XPS, XRD and single crystal X-ray diffraction analyses. Compound 1 exhibits a 1-D chain structure constructed from Pseudo-Keggin polyoxometalate bi-supported transition metal coordination complexes linked by K + ions. Compound 2 contains Pseudo-Keggin polyoxoanions [HPW 12O 40] 2− and novel metal–chloride–ligand coordination complexes [Cd 2( Phen) 4Cl 2] 2+.
