Structure d'un Diphosphate Synthétique de Cobalt: Co₂P₂O₇

The title compound, a new polymorphic phase of dicobalt diphosphate, Co₂P₂O₇, was prepared by hydrothermal methods. The structure contains CoO₆ coordination octahedra and P₂O₇ radicals. The CoO₆ radicals, connected by edge sharing, form six-membered rings, which are further interconnected to form two-dimensional zigzag sheets parallel to (001). The P₂O₇ groups link these sheets to build three-dimensional networks.
