摘要

The crystal structure of the new indium phosphate In3P2Og has been determined from single crystal data. The unit cell is cubic [space group I43d (Z = 8)] with a = 11.152(1) A. The structure is characterized by a three-dimensional arrangement of isolated PO4" tetra-hedra forming the anionic network, while the electro-neutrality is insured by (In-In)4+ cationic pairs. The In-In distance, equal to 2.630(1)A, is the shortest In-In bond ever found. Powdered In3P2O8 can be synthesized from a mixture of 4 InPO4:l In2O3 after thermal reduction under H2.
