Materials Data on CoGe by Materials Project

Abstract

CoGe is Modderite-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Co sites. In the first Co site, Co is bonded in a 6-coordinate geometry to four Co and six Ge atoms. There are two shorter (2.46 Å) and two longer (2.58 Å) Co–Co bond lengths. There are four shorter (2.40 Å) and two longer (2.46 Å) Co–Ge bond lengths. In the second Co site, Co is bonded in a 6-coordinate geometry to four Co and six Ge atoms. Both Co–Co bond lengths are 2.59 Å. There are four shorter (2.38 Å) and two longer (2.44 Å) Co–Ge bond lengths. In the third Co site, Co is bonded in a 6-coordinate geometry to two Co and six Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.38–2.52 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 6-coordinate geometry to six Co atoms. In the second Ge site, Ge is bonded in a 6-coordinate geometry to six Co atoms.
