dc.description.abstract | <p>Cd<sub>2</sub>P<sub>2</sub>O<sub>7</sub> has been found to belong to the space group Γ 1. The structure has a bent P-O(b)-P bond angle for the anion with the central oxygen O(b) close to sp<sup>2</sup> hybridization. The two PO<sub>4</sub> tetrahedra forming the anion are eclipsed. The cadmium atoms are sixfold co-ordinated to oxygen atoms forming two types of distorted octahedra.</p> <p>Cd<sub>2</sub>V<sub>2</sub>O<sub>7</sub> belongs to the monoclinic space group C 2/m. As with most structures in the thortveitite series that have been determined, the central oxygen in V<sub>2</sub>O<sub>7</sub><sup>4-</sup> ion shows enhanced thermal motion. The cadmium atoms are also sixfold co-ordinated to oxygen atoms forming distorted octahedra.</p> <p>The bonding in P<sub>2</sub>O<sub>7</sub><sup>4-</sup> ion is discussed with reference to values predicted by Cruickshank, and those in the V<sub>2</sub>O<sub>7</sub><sup>4-</sup> ion compared with values calculated by Barnes and Bachmann.</p> | en_US |
