Description:
The crystal structure of the title compound, Cd2P2O7, has been reinvestigated by means of an image-plate diffraction system. The study confirms the previously determined structure [Calvo & Au (1969). Can. J. Chem. 47, 3409–3417], but provides a less biased model and higher precision. The structure consists of alternating layers of isolated P2O7 groups and edge-sharing CdO6 octahedra forming corrugated chains along [1overline{1}0]. The layers and the parallel chains interconnect by means of corner-sharing. This room-temperature structure is actually the average of a modulated structure, which might partly rectify the unusual bond valences.
