Materials Data on Ca3(GaPd)2 by Materials Project
Ca3(PdGa)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Ca sites. In the first Ca site, Ca is bonded in a 6-coordinate geometry to four equivalent Pd and five Ga atoms. There are a spread of Ca–Pd bond distances ranging from 3.04–3.17 Å. There are a spread of Ca–Ga bond distances ranging from 3.13–3.48 Å. In the second Ca site, Ca is bonded in a 7-coordinate geometry to four equivalent Pd and three equivalent Ga atoms. There are two shorter (3.18 Å) and two longer (3.19 Å) Ca–Pd bond lengths. There are a spread of Ca–Ga bond distances ranging from 3.07–3.21 Å. Pd is bonded in a 9-coordinate geometry to six Ca and three Ga atoms. There are a spread of Pd–Ga bond distances ranging from 2.59–2.64 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 12-coordinate geometry to six equivalent Ca and four equivalent Pd atoms. In the second Ga site, Ga is bonded in a 9-coordinate geometry to seven Ca and two equivalent Pd atoms.
