Abstract
Dipotassium molybdenyl diphosphate is built up from ribbons of MoO6 octahedra linked to P2O7 groups running along the c axis. The K+ cations are located in the channels delimited by anionic (MoO2P2O7)n ribbons. The structure contains MoP2O11 units, in which each P2O7 group shares two of its apices with an MoO6 octahedron. The title compound is isotypic with (NH4)2MoO2P2O7. K2MoO2P2O7 (one-dimensional) is related structurally to Na2VOP2O7 (two-dimensional) and β-BaV2(P2O7)2 (three-dimensional), all of them being built up from MP2O11 (M = Mo, V) units.
