Materials Data on K2U(SO6)2 by Materials Project
K2U(SO6)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of K–O bond distances ranging from 2.72–3.02 Å. U is bonded to seven O atoms to form distorted UO7 pentagonal bipyramids that share corners with four equivalent SO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.81–2.40 Å. S is bonded to four O atoms to form SO4 tetrahedra that share corners with two equivalent UO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.47–1.53 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to two equivalent K atoms. In the second O site, O is bonded in a 1-coordinate geometry to one K, one U, and one S atom. In the third O site, O is bonded in a distorted single-bond geometry to two equivalent K and one S atom. In the fourth O site, O is bonded in a single-bond geometry to one U atom. In the fifth O site, O is bonded in a single-bond geometry to one U atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two equivalent K and one S atom. In the seventh O site, O is bonded in a single-bond geometry to one U atom. In the eighth O site, O is bonded in a 1-coordinate geometry to one K, one U, and one S atom.
