Materials Data on Co2Ge by Materials Project

Abstract

Co2Ge is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Co sites. In the first Co site, Co is bonded in a 4-coordinate geometry to six equivalent Co and five equivalent Ge atoms. There are a spread of Co–Co bond distances ranging from 2.57–2.73 Å. There are a spread of Co–Ge bond distances ranging from 2.35–2.72 Å. In the second Co site, Co is bonded in a 5-coordinate geometry to eight Co and five equivalent Ge atoms. Both Co–Co bond lengths are 2.57 Å. There are a spread of Co–Ge bond distances ranging from 2.41–2.62 Å. Ge is bonded in a 10-coordinate geometry to ten Co atoms.
