Title: Materials Data on K2U2MoO10 by Materials Project

Abstract

K2(UO2)2(MoO4)O2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first 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 2.78–2.95 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.75–3.19 Å. There are two inequivalent U6+ sites. In the first U6+ site, U6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of U–O bond distances ranging from 1.85–2.42 Å. In the second U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent MoO4 tetrahedra and an edgeedge with one UO7 pentagonal bipyramid. There are a spread of U–O bond distances ranging from 1.84–2.62 Å. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent UO7 pentagonal bipyramids. There are a spread of Mo–O bond distances ranging from 1.77–1.83 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bondedmore » in a 1-coordinate geometry to three K1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to three U6+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one U6+, and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one K1+ and three U6+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one U6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one U6+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one U6+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one U6+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one Mo6+ atom.« less
