摘要：

A new Mo(V) phosphate BaMo2P4O16 has been synthesized and its structure has been determined from a single crystal X-ray diffraction study. It crystallizes in the space group P21 c with a = 6.4394(4) Å, b = 12.378(1) Å, c = 9.1613(7) Å, β = 123.92(1)°. The original [Mo2P4O16]∝ host lattice shows that it is the only diphosphate of pentavalent molybdenum known up to now. Each P2O7 group shares two corners with the same MoO6 octahedron forming [MoP2O11] units already encountered in the AMo2P3O13 phosphates. The whole structure can be described from these structural units, which share their corners leading to [MoP2O10]∞ chains running along b. One important characteristic of this tridimensional framework deals with the fact that each MoO6 octahedron and each P2O7 group exhibit one free apex, suggesting a great flexibility of the structure. © 1990.
