Ametavanadate in coffe colour,V2O6·H3NCH2CH2NH3,was synthesized by hydrothermal method and its crystal structure was determined by single crystal X-ray diffrac tion,Crystal data:monoclinic, space group P21/c,a=0.552 9(2) nm,b=1.290 0(7) nm,c=0.5683(2) nm,β=97.57(3)°,V=0.4018(3) nm3,F(000)=260,De=2.15 g·cm(-3),Z=2,R=0.041,Rw=0.052.The structure is based on VO4 tetrahedra sharing two vertex to form a single type of chain running along the c axis. The hydrogen bond(O…H N)be tween chains and was formed.IR spectrum confirmed that the ethylenediamine is protonated.The analysis of DRS and SPS are given.
