Materials Data on K2UP2(H2O5)2 by Materials Project
Abstract
K2UP2(H2O5)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.76–3.19 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.77–2.97 Å. U4+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with five PHO3 tetrahedra. There are a spread of U–O bond distances ranging from 1.82–2.41 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with three equivalent UO7 pentagonal bipyramids. The P–H bond length is 1.41 Å. All P–O bond lengths are 1.54 Å. In the second P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent UO7 pentagonal bipyramids. The P–H bond length is 1.42 Å. There are a spread of P–O bond distances rangingmore »
