2D Rhombus-grid networks constructed from vanadium-substituted Keggin-type polyoxomolybdophosphates and Cd/Zn complex fragments

Two new organic–inorganic hybrid compounds [{M(2,2′-bpy)2}2{PMo11VO40}] (M=Cd(1), Zn(2); bpy=2,2′-bipyridine) have been hydrothermally synthesized and characterized. In compounds, Keggin-anions [PMo11VO40]4−, as the nodes of the grid, connect with [M(2,2′-bipy)2]2+ fragments to form a rhombus-grid layered structure.
