Abstract

Intense blue powder samples of (NH4)Zn(H2O)(VO)2(PO4)2(H2PO4) were prepared in quantitative yield from hydrothermal treatments. (NH4)Zn(H2O)(VO)2(PO4)2(H2PO4) is monoclinic, space group P21/n with parameters a = 10.7451(1) Å, b = 9.1941(1) Å, c = 13.2112(2) Å, β = 103.657(1)°, Z = 4 (R1(Fo) = 0.030, wR2(Fo2) = 0.047). The structure is based on linking of fused octahedra V2O9 with tetrahedra HxPO4 and ZnO3(H2O). The remaining tunnels of the 3D framework [Zn(H2O)(VO)2(PO4)2(H2PO4)]− are occupied by the ammonium cations. The susceptibility data are consistent with the presence of dimers containing V4+ and small amounts of non-magnetic V5+ with strong antiferromagnetic coupling (J ∼ −29 cm−1).
