摘要：

On the basis of the distances A-X and B-X, in the defect pyrochlores A2B2O6, a general approach to the coordination polyhedra around A and B metal ions is established. Results show that, depending on these distances, coordination of 3 + 3 and 3 + 3 + 3 around A ions can be found and that a region of low stability should exist.
