Materials Data on Ca3Ge3Au8 by Materials Project
Abstract
Ca3Au8Ge3 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are four inequivalent Ca sites. In the first Ca site, Ca is bonded in a 10-coordinate geometry to eleven Au and five Ge atoms. There are a spread of Ca–Au bond distances ranging from 3.18–3.73 Å. There are a spread of Ca–Ge bond distances ranging from 3.16–3.37 Å. In the second Ca site, Ca is bonded in a 10-coordinate geometry to eleven Au and three Ge atoms. There are a spread of Ca–Au bond distances ranging from 3.15–3.45 Å. There are two shorter (3.22 Å) and one longer (3.42 Å) Ca–Ge bond lengths. In the third Ca site, Ca is bonded in a 8-coordinate geometry to ten Au and two equivalent Ge atoms. There are a spread of Ca–Au bond distances ranging from 3.09–3.63 Å. Both Ca–Ge bond lengths are 3.20 Å. In the fourth Ca site, Ca is bonded in a 12-coordinate geometry to twelve Au atoms. There are a spread of Ca–Au bond distances ranging from 3.17–3.64 Å. There are nine inequivalent Au sites. In the first Au site, Au is bonded in a 10-coordinate geometry to four Ca, four Au, and two equivalent Gemore »
