Materials Data on Ce(SO6)2 by Materials Project

Abstract

Ce(SO6)2 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Ce(SO6)2 sheets oriented in the (0, 0, 1) direction. Ce is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ce–O bond distances ranging from 2.12–2.48 Å. S is bonded in a tetrahedral geometry to four O atoms. There is three shorter (1.48 Å) and one longer (1.50 Å) S–O bond length. There are seven inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one S atom. In the second O site, O is bonded in a bent 150 degrees geometry to one Ce and one S atom. In the third O site, O is bonded in a single-bond geometry to one Ce atom. In the fourth O site, O is bonded in a single-bond geometry to one Ce atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Ce and one S atom. In the sixth O site, O is bonded in a single-bond geometry to one Ce atom. In the seventh O site, O is bonded in a single-bond geometry to one S atom.
