摘要：

The diphosphate structures A2P2O7 contain P2O7 anions which show an eclipsed (dichromate-type) or staggered (thortveitite-type) spatial conformation. The first class is related to large ions A(II) (A = Ca, Sr, Ba, Cd, Pb), while the second family includes small cations (A = Mg, Mn, Fe, Co, Ni, Cu, Zn). In the mixed phosphates (A,B)2P2O7, where A and B are bivalent ions, the type of structure is generally controlled by the largest cation.
