A new Mo(V) phosphate BaMo{sub 2}P{sub 4}O{sub 16} has been synthesized and its structure has been determined from a single crystal x-ray diffraction study. It crystallizes in the space group P2{sub 1}/c with a = 6.4394(4) {angstrom}, b = 12.378(1) {angstrom}, c = 9.1613(7) {angstrom}, {beta} = 123.92(1){degree}. The original (MO{sub 2}P{sub 4}O{sub 16}){sub {infinity}} host lattice shows that it is the only diphosphate of pentavalent molybdenum known up to now. Each P{sub 2}O{sub 7} group shares two corners with the same MoO{sub 6} octahedron forming (MoP{sub 2}O{sub 11}) units already encountered in the AMo{sub 2}P{sub 3}O{sub 13} phosphates. The whole structure can be described from these structural units, which share their corners leading to (MoP{sub 2}O{sub 10}){sub {infinity}} chains running along {rvec b}. One important characteristic of this tridimensional framework deals with the fact that each MoO{sub 6} octahedron and each P{sub 2}O{sub 7} group exhibit one free apex, suggesting a great flexibility of the structure.
