Materials Data on Ca(ReO5)2 by Materials Project

Abstract

Ca(ReO5)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ca is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.36–2.66 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded in a tetrahedral geometry to four O atoms. There are a spread of Re–O bond distances ranging from 1.73–1.81 Å. In the second Re site, Re is bonded in a tetrahedral geometry to four O atoms. There is one shorter (1.73 Å) and three longer (1.76 Å) Re–O bond length. There are ten inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Re atom. In the second O site, O is bonded in a bent 120 degrees geometry to two equivalent Ca atoms. In the third O site, O is bonded in a distorted bent 150 degrees geometry to one Ca and one Re atom. In the fourth O site, O is bonded in a distorted bent 150 degrees geometry to one Ca and one Re atom. In the fifth O site, O is bonded in a linear geometry to one Ca and one Re atom. In the sixth O site, O is bonded in a linear geometry to one Ca and one Re atom. In the seventh O site, O is bonded in a single-bond geometry to one Re atom. In the eighth O site, O is bonded in a single-bond geometry to one Re atom. In the ninth O site, O is bonded in a single-bond geometry to one Ca atom. In the tenth O site, O is bonded in a bent 150 degrees geometry to one Ca and one Re atom.
