Hydrothermal Synthesis and Crystal Structure of Na_2In_2[PO_3(OH)]_4 centre dot H_2O with a New Structure Type

摘要

A sodium indium hydrogen phosphate hydrate, Na2In2 [P03 (OH)]4. H20, was synthesized under mild hydrothermal condi-dons, and the crystal structure was characterized by the single-crystal X-ray diffraction method. The structure is of a new type with the following data: Mr = 794.775, triclinic, aP62, P-i (No. 2), a 9.3013(1) A, b = 9.4976(1) A, c = 9.2685(7) A, ~ =98.710(4)0, 1
