| Abstract: | A polyoxovanadate NH3(CH2)4NH3]2V10O28]·6H2O(1,pip=piperazine) has been synthesized by hydrothermal method and characterized by elemental analysis,IR,TGA and single-crystal X-ray diffraction.Compound 1 crystallizes in the monoclinic system,space group P21/n,with cell parameters of a=1.229 85(10) nm,b=1.075 10(9) nm,c=1.496 71(12) nm,β=93.947 0(10)°,V=1.974 3(3) nm3,Z=2.Crystallographic analysis reveals that it is constructed from anionic cluster V10O28]6-,protonated 1,4-butanediamine and piperazine cations,as well as waters of crystallization.Organic cations and waters of crystallization further connect the anions into a three-dimensional framework by water-anion hydrogen bonds O-H…O and cation-anion N-H…O interactions.CCDC: 848090. |
