Abstract:
A novel molybdophosphate supermolecular compound (bipyH2)2(H2P2Mo5O 23) · H2O has been synthesized by hydrothermal method and characterized by crystal X-ray structure analysis, IR spectrum, Raman spectrum, UV-Vis DRIS spectrum, fluorescence spectrum and CV. The crystal belongs to monoclinic system with a space group P21/c, a=1.679 51(7) nm, b=1.151 93(4) nm, c=1.889 08(8) nm, β=108.335(1)°, V=3.469 2(2) nm3, Z=4, Dc=2.382 g/cm3, F(000)=2 408, μ=1.951 mm-1, R=0.024 4, Rw=0.072 1. The heteropoly anion[H2P2Mo5O23]4- and protonated 4,4 prime -bipy are connected to a supermolecular compound by hydrogen bonds; and the anions contain five MoO6 octahedra and two PO4 tetrahedron; Mo, P atoms show a distorted pentagonal bipyramidal configuration, and the heteropoly anions are connected to a infinite planar structure with the protonated 4,4 prime -bipy.
