Materials Data on Ca3Ga3Ir2 by Materials Project

Abstract

Ca3Ir2Ga3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ca sites. In the first Ca site, Ca is bonded in a 10-coordinate geometry to three equivalent Ir and seven Ga atoms. There are a spread of Ca–Ir bond distances ranging from 3.06–3.22 Å. There are a spread of Ca–Ga bond distances ranging from 3.13–3.46 Å. In the second Ca site, Ca is bonded in a 7-coordinate geometry to four equivalent Ir and five Ga atoms. There are two shorter (3.16 Å) and two longer (3.38 Å) Ca–Ir bond lengths. There are a spread of Ca–Ga bond distances ranging from 2.96–3.41 Å. Ir is bonded in a 4-coordinate geometry to five Ca and four Ga atoms. There are a spread of Ir–Ga bond distances ranging from 2.50–2.54 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to seven Ca and two equivalent Ir atoms. In the second Ga site, Ga is bonded in a 9-coordinate geometry to six Ca and three equivalent Ir atoms.
