Hydrothermal synthesis and structural characterization of a new layered vanadium selenite: (C4N2H12)0.5[(VO)2(H2O)2(SeO3)2(HSeO3)]

A layered vanadium selenite, (C4N2H12)0.5[(VO)2(H2O)2(SeO3)2(HSeO3)], has been hydrothermally synthesized and structurally characterized. Its structure is layered and can be described as vanadium selenite oxide layers with diprotonated piperazine occupying the interlayer space. The result of magnetic measurement for the title compound shows a typical antiferromagnetic interaction at low temperature.
