Hydrothermal Synthesis and Crystal Structure of a Three-dimensionalOpen-framework Compound, {[Cu(1,2-pn)-2]_4[V_(18)O_(42)(H_2O)]}_n·8nH_2O

<正>物材多孔材料广泛应用于吸附、形状和尺寸选择性的多相催化和离子交换．利用有机胺分子的模板和结构导向作用已设计合成了许多沸石分子筛、中孔MCM－41和非致密过渡金属磷酸盐等多孔性氧化料[’－“．过渡金属氧簇结构中普遍存在金属－金属键。

The hydrothermal reaction of V2O5, Cu(CH3COO)2 . H2O, TMAOH and 1,2-diaminopropane gave a novel three-dimensional framework material, {[Cu(1,2-pn)2]4[V18O42(H2O)]}n . 8nH2O, which was constructed from the mixed-valence {V18O42(H2O)} clusters interconnected through {Cu(1,2-pn)2} complex groups. {[Cu(1,2-pn)2]4[V18O42(H2O)]}n . 8nH2O was characterized by IR, TGA and single-crystal X-ray diffraction. It crystallizes in tetragonal space group P4/nnc with a=1. 510 7(2) nm, c = 1.864 5(4) nm, Dc = 2. 028 g/cm3, Z = 2, R1= 0.063 1, wR2 = 0.153 8.
