| Popis: | The hydrothermal synthesis, X-ray single crystal structure, and some properties of BaVO(PO4)(H2PO4) · H2O are described. BaVO(PO4)(H2PO4) · H2O is built up from VO6 and (H2)PO4 groups, linked via V-O-P bonds, into anionic VO(PO4)(H2PO4) layers. The 9-coordinate Ba2+ cations and water molecules provide the interlayer packing between the V/P/O/H sheets. Magnetic susceptibility measurements on BaVO(PO4)(H2PO4) · H2O show perfect Curie-Weiss paramagnetism down to 4 K. Powder X-ray, TGA, and IR data for BaVO(PO4)(H2PO4) · H2O are also presented. Crystal data: BaVO(PO4)(H2PO4) · H2O, M = 414.24, monoclinic, space group P21/n (No. 14), a = 10.848 (3) A, b = 6.408(3) A, c = 11.376(2) A, β = 102.32(2)°, V = 773(2) A3, Z = 4, R(F) = 2.24%, Rw(F) = 2.42% [141 parameters; 2103 reflections with I > 3 σ (I)]. |
