Abstract

Two layered vanadyl selenites with the compositions, [DABCOH2]0.5[(VIVO)(HSeO3)(SeO3)]·H2O, I, and [enH2][(VivO)2(VVO)O2(SeO3)3]-·1.25H2O, II, have been prepared by the reaction of NaVO3 with SeO2 or H2SeO4 under hydrothermal conditions in the presence of organic amines. Crystal data: I, orthorhombic, space group Pbcn (No. 60), a=6.3152(3) Å, b=18.1918(8) Å, c=17.7172(8) Å, V=2035.4(2) Å3, Z=8, R1(all data)=0.0368; II, triclinic, space group P↑(No.2), a=6.3406(2) Å, b=10.2085(3) Å, c=13.2551(10) Å, α=101.238(2)°, β=96.503(2)°, γ=104.332(2)°, V=803.47(4) Å3, Z=2, R1(all data)=0.0814. While I contains the ladder motif, commonly found in open-framework metal phosphates, II is formed by a secondary building unit composed of a V4O18 cluster along with SeO3 and VO5 groups. The study demonstrates that the selenite unit can be fruitfully exploited to design interesting open-framework structures.
