Materials Data on CaAlAu by Materials Project
CaAuAl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ca is bonded in a 5-coordinate geometry to five equivalent Au and six equivalent Al atoms. There are a spread of Ca–Au bond distances ranging from 3.07–3.24 Å. There are a spread of Ca–Al bond distances ranging from 3.18–3.45 Å. Au is bonded in a 9-coordinate geometry to five equivalent Ca and four equivalent Al atoms. There are two shorter (2.69 Å) and two longer (2.71 Å) Au–Al bond lengths. Al is bonded in a 4-coordinate geometry to six equivalent Ca and four equivalent Au atoms.
