Materials Data on CaAlSi by Materials Project
Abstract
CaAlSi crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are five inequivalent Ca sites. In the first Ca site, Ca is bonded to six Al and six Si atoms to form a mixture of distorted edge and face-sharing CaAl6Si6 cuboctahedra. There are three shorter (3.41 Å) and three longer (3.43 Å) Ca–Al bond lengths. There are three shorter (3.16 Å) and three longer (3.17 Å) Ca–Si bond lengths. In the second Ca site, Ca is bonded to six Al and six Si atoms to form a mixture of distorted edge and face-sharing CaAl6Si6 cuboctahedra. There are three shorter (3.41 Å) and three longer (3.42 Å) Ca–Al bond lengths. There are three shorter (3.16 Å) and three longer (3.17 Å) Ca–Si bond lengths. In the third Ca site, Ca is bonded to six Al and six Si atoms to form a mixture of edge and face-sharing CaAl6Si6 cuboctahedra. There are three shorter (3.15 Å) and three longer (3.25 Å) Ca–Al bond lengths. There are three shorter (3.24 Å) and three longer (3.39 Å) Ca–Si bond lengths. In the fourth Ca site, Ca is bonded to six Al and six Si atoms to form a mixture of edgemore »
