| Abstract: | The hydrothermal reactions of NH4VO3, Cu(NO3)2·H2O or Cu(CH3CO2)2·H2O As2O5 and the appropriate organonitrogen ligand in the presence of HF as mineralizer yield a series of bimetallic oxides of the Cu/V/O/As family. The materials Cu(bpy)(VO2)(AsO4)] (1) and Cu(bpy)VO2(OH)(AsO4H)]·H2O (2·H2O) are one-dimensional (bpy = 2,2′-bipyridine). While phase 1 is constructed from  chains decorated by {Cu(bpy)}2+ groups, compound 2 consists of {V2O4(OH)2(AsO4H)2}2− clusters linked through {Cu(bpy)}2+ subunits. In contrast, the structure of Cu2(bpyrm)(VO2)2(AsO4)2]·H2O (3·H2O) is three-dimensional, consisting of  layers, linked through {Cu2(bpyrm)}4+ rods (bpyrm = bipyrimidine). |
