Title: Materials Data on CaCuGe by Materials Project

Abstract

CaCuGe crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are three inequivalent Ca sites. In the first Ca site, Ca is bonded in a 12-coordinate geometry to six Cu and six Ge atoms. There are a spread of Ca–Cu bond distances ranging from 2.95–3.23 Å. There are a spread of Ca–Ge bond distances ranging from 3.00–3.25 Å. In the second Ca site, Ca is bonded in a 12-coordinate geometry to six Cu and six Ge atoms. There are a spread of Ca–Cu bond distances ranging from 3.14–3.27 Å. There are a spread of Ca–Ge bond distances ranging from 3.00–3.11 Å. In the third Ca site, Ca is bonded in a 12-coordinate geometry to six Cu and six Ge atoms. There are a spread of Ca–Cu bond distances ranging from 3.04–3.11 Å. There are a spread of Ca–Ge bond distances ranging from 3.12–3.27 Å. There are three inequivalent Cu sites. In the first Cu site, Cu is bonded in a 10-coordinate geometry to six Ca, one Cu, and three Ge atoms. The Cu–Cu bond length is 2.97 Å. There are two shorter (2.51 Å) and one longer (2.54 Å) Cu–Ge bond lengths. In the second Cu site,more » Cu is bonded in a 10-coordinate geometry to six Ca, one Cu, and three equivalent Ge atoms. There are two shorter (2.52 Å) and one longer (2.61 Å) Cu–Ge bond lengths. In the third Cu site, Cu is bonded in a 10-coordinate geometry to six Ca and four Ge atoms. There are a spread of Cu–Ge bond distances ranging from 2.53–2.85 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Ca, three Cu, and one Ge atom. The Ge–Ge bond length is 2.74 Å. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Ca, three equivalent Cu, and one Ge atom. In the third Ge site, Ge is bonded in a 10-coordinate geometry to six Ca and four Cu atoms.« less
