Materials Data on Tb3Co2Ge3 by Materials Project

Abstract

Tb3Co2Ge3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 11-coordinate geometry to four equivalent Co and seven Ge atoms. There are a spread of Tb–Co bond distances ranging from 3.02–3.16 Å. There are a spread of Tb–Ge bond distances ranging from 2.99–3.22 Å. In the second Tb site, Tb is bonded in a 9-coordinate geometry to four equivalent Co and five Ge atoms. All Tb–Co bond lengths are 3.11 Å. There are a spread of Tb–Ge bond distances ranging from 2.94–3.21 Å. Co is bonded in a 10-coordinate geometry to six Tb and four Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.38–2.56 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Tb and two equivalent Co atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Tb, three equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.92 Å.
