A mixed indium–iron lithium diphosphate, In0.51Fe0.49LiP2O7

The structure of In0.51Fe0.49LiP2O7 consists of a three-dimensional network constructed from (InIII/FeIII)O6 octahedra and P2O7 groups. Each MIIIO6 octahedron is linked to six PO4 tetrahedra belonging to five different P2O7 groups and shares two corners with the same P2O7 group so as to build infini...

Description
Summary:The structure of In0.51Fe0.49LiP2O7 consists of a three-dimensional network constructed from (InIII/FeIII)O6 octahedra and P2O7 groups. Each MIIIO6 octahedron is linked to six PO4 tetrahedra belonging to five different P2O7 groups and shares two corners with the same P2O7 group so as to build infinite chains or rather parallel colums of [MIIIP2O11] running along the a axis. The linkage between these chains or columns defines heptagonal tunnels parallel to [100] in which the Li+ ions are located in off-centred positions. The In0.51Fe0.49LiP2O7 compound can be regarded as one composition of the continuous solid solution between LiFeP2O7 and LiInP2O7 whose structure is isotypic with the AIFeP2O7 (AI = Na, K, Rb, Cs and Ag) diphosphate family.
