摘要(英) |
Two Zinc Vanadium Phosphates, Zn(VO)2(PO4)2(H2O)4 (A1) and [(VVO)(VIVO)3Zn2(OH)(PO4)4(H2O)7]‧H2O (A2), were synthesized under mild hydrothermal conditions. Both of these two structures were determined by single-crystal X-ray diffraction. The purity of each compound was confirmed by powder X-ray diffraction. These compounds were further characterized by TGA, SQUID, XPS.
The reaction agent ratio of A1 and A2 are same, but reaction temperature are different, A1 is a Vanadium(IV) compound, A2 is a mixed-valance compound, the reducing agent zinc maybe play a big role in this reactions to show this results. Magnetic Susceptibility also can proof A2 is a mixed-valance vanadium compound.
A1 crystal data: Zn(VO)2(PO4)2(H2O)4, tetragonal, I4/m(No. 87), a = 6.2518(2) Å, c = 13.4642(6) Å, V = 526.25(3) Å3, Z = 2, R1 = 0.0481 and wR2 = 0.1144.
A2 crystal data: [(VVO)(VIVO)3Zn2(OH)(PO4)4(H2O)7]‧H2O, monoclinic, I4/m(No. 87), a = 12.6432(6) Å, b = 12.6408(6) Å, c = 13.5881(6) Å, =108.627(2)°, V = 2057.90(17) Å3, Z = 4, R1 = 0.0202 and wR2 = 0.0570.
