Hydrothermal synthesis and crystal structure of a new oxovandate

An oxovandium component Cu(C2H4N2) V2O6 is synthesized by CuSO4、NH4VO3 and En in hydrothermal method and reacted in the condition of 180℃ high pressure.At the same time,X-ray structural diffraction is characterized with crystal's cell parameter:a=5.786 1(12)nm,b=8.161 7(16)nm,c= 17.523(4)nm,α=90.00°,β=90.43(3)°,γ= 90.00°,Z= 827.5(3),D= 2.323,F_000 = 546,R1= 0.028 8,and Wr=0.079 5.Cu is six coordinate atom forming octahedron.V1 and V2 are both four V-O coordinate atoms forming tetrahedron.The single molecules are connected to a 1D chain structure,and a 2D net structure is synthesized between the chains.
