Organic-inorganic hybrid materials constructed from Cu(II)-organonitrogen coordination complex cations and oxovanadium-arsonate subunits

Hydrothermal reactions were exploited in the syntheses of a series of materials of copper(II)/oxovanadate/arsonate family. [Cu(bpy)(VO2)(AsO4)] (1) and [Cu(bpy)VO2(OH)(AsO4H)]·H2O (2·H2O) are one-dimensional, while the structure of [Cu2(bpyrm)(VO2)2(AsO4)2]·H2O (3·H2O) (shown here) is three-dimensional, consisting of {VO2(AsO4)}n2n- layers, linked through {Cu2(bpyrm)}4+ rods (bpyrm = bipyrimidine).
