Abstract
A metavanadate in coffee colour, V2O6 · H3NCH2CH2NH3, was synthesized by hydrothermal method and its crystal structure was determined by single crystal X-ray diffraction. Crystal data: monoclinic, space group P21/c, a = 0.552 9(2) nm, b=1.290 0(7) nm, c=0. 568 3(2) nm, β=97. 57(3)°, V=0.401 8(3) nm3, F(000)=260, Dc=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) between (VO3-)∞ chains and H3NCH2CH2NH32+ was formed. IR spectrum confirmed that the ethylenediamine is protonated. The analysis of DRS and SPS are given.
