TlHP₂O₇: structure determination from X-ray powder diffraction data

L. S. Ivashkevich, K. A. Selevich, A. S. Lyakhov and A. F. Selevich

Abstract: The crystal structure of monoclinic thallium(III) hydrogendiphosphate, TlHP₂O₇, has been solved from laboratory X-ray powder diffraction data and refined by the Rietveld method. All atoms occupy general positions. The Tl^III ions have a distorted octahedral coordination environment of O atoms from four diphosphate groups. Adjacent TlO₆ octahedra form edge-shared Tl₂O₁₀ dimers which share corners with PO₄ tetrahedra to build a three-dimensional polymeric structure.
