Materials Data on Ca2Zn3Ga by Materials Project
Ca2Zn3Ga crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Ca sites. In the first Ca site, Ca is bonded in a 12-coordinate geometry to nine Zn and three equivalent Ga atoms. There are a spread of Ca–Zn bond distances ranging from 3.14–3.35 Å. There are one shorter (3.26 Å) and two longer (3.33 Å) Ca–Ga bond lengths. In the second Ca site, Ca is bonded in a 12-coordinate geometry to nine Zn and three equivalent Ga atoms. There are a spread of Ca–Zn bond distances ranging from 3.12–3.32 Å. There are two shorter (3.15 Å) and one longer (3.20 Å) Ca–Ga bond lengths. There are three inequivalent Zn sites. In the first Zn site, Zn is bonded in a 10-coordinate geometry to six Ca, three Zn, and one Ga atom. There are two shorter (2.63 Å) and one longer (2.92 Å) Zn–Zn bond lengths. The Zn–Ga bond length is 2.66 Å. In the second Zn site, Zn is bonded in a 10-coordinate geometry to six Ca, two Zn, and two equivalent Ga atoms. The Zn–Zn bond length is 2.69 Å. Both Zn–Ga bond lengths are 2.63 Å. In the third Zn site, Zn is bonded in a 10-coordinate geometry to six Ca, three Zn, and one Ga atom. The Zn–Ga bond length is 2.86 Å. Ga is bonded in a 10-coordinate geometry to six Ca and four Zn atoms.
