Materials Data on Tb2Co3Ge5 by Materials Project

Abstract

Tb2Co3Ge5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Tb is bonded in a 1-coordinate geometry to ten Ge atoms. There are a spread of Tb–Ge bond distances ranging from 2.89–3.22 Å. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 9-coordinate geometry to five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.31–2.42 Å. In the second Co site, Co is bonded in a 12-coordinate geometry to six Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.41–2.69 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Tb and four equivalent Co atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Tb, three Co, and two Ge atoms. There are one shorter (2.65 Å) and one longer (2.66 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 5-coordinate geometry to four equivalent Tb, three Co, and four Ge atoms. Both Ge–Ge bond lengths are 2.87 Å. In the fourth Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Tb, three Co, and four Ge atoms.
