主　　题：hydrothermal molybdenum phosphate crystal structure 

摘      要：The title compound (C5N5H41P2Mo5O30.5) was synthesized under hydrothermal condition and its crystal structure was determined by X-ray diffraction. It belongs to triclinic system, space group P , with a=9.9645(6), b=10.8666(7), c=15.814(1)? α=71.482(3), β=88.528(2), γ=78.448(2)°, V=1589.4(2)3, Dc=2.510g/cm3, Z=2,μ=2.138mm-1,λ(MoKα) = 0.71073 ? F(000)=1180. The final R and wR were 0.0396 and 0.1052 for 6626 observed reflections with I ≥2σ(I), respectively. The result of the structure analysis indicates that the [Mo5O15(PO4) (HPO4)]5- anion in the title compound consists of five edge-sharing or corner-sharing MoO6 octahedra and two corner-sharing PO4 tetrahedra. Each MoO6 octahedron adopts distorted octahedral geometry.
