| Abstract: | A novel molybdenum diphosphate, Mo1.3O(P2O7), was obtained by electrochemical lithium deintercalation. The diphosphate crystallises in space group I2/a with the lattice parameters a=22.88(1), b=22.94(2), c=4.832(1) Å, γ=90.36°, Z=8. Its original framework is built up from MoO6 octahedra, P2O7 groups and also from MoO4, Mo2O4 and Mo3O8 units containing Mo2 and Mo3 clusters. These polyhedra delimit large octagonal and z-shaped tunnels running along c, in which the inserted cations may be located. |
