Materials Data on Ce4Ge7 by Materials Project

Abstract

Ce4Ge7 crystallizes in the orthorhombic C222_1 space group. The structure is three-dimensional. there are three inequivalent Ce sites. In the first Ce site, Ce is bonded in a 9-coordinate geometry to eleven Ge atoms. There are a spread of Ce–Ge bond distances ranging from 3.07–3.71 Å. In the second Ce site, Ce is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ce–Ge bond distances ranging from 3.08–3.31 Å. In the third Ce site, Ce is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ce–Ge bond distances ranging from 3.04–3.27 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to six Ce and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.61 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Ce and three Ge atoms. There are one shorter (2.59 Å) and one longer (2.62 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 4-coordinate geometry to six Ce and three Ge atoms. There are one shorter (2.69 Å) and one longer (3.00 Å) Ge–Ge bond lengths. In the fourth Ge site, Ge is bonded in a 9-coordinate geometry to six Ce and three Ge atoms. The Ge–Ge bond length is 2.52 Å.
