Materials Data on K4Si23 by Materials Project
Abstract
K4Si23 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to twenty Si+0.17- atoms. There are eight shorter (3.31 Å) and twelve longer (3.40 Å) K–Si bond lengths. In the second K1+ site, K1+ is bonded in a 12-coordinate geometry to twelve Si+0.17- atoms. There are eight shorter (3.49 Å) and four longer (3.66 Å) K–Si bond lengths. In the third K1+ site, K1+ is bonded in a 12-coordinate geometry to twelve Si+0.17- atoms. There are eight shorter (3.49 Å) and four longer (3.66 Å) K–Si bond lengths. There are ten inequivalent Si+0.17- sites. In the first Si+0.17- site, Si+0.17- is bonded in a 7-coordinate geometry to three K1+ and four Si+0.17- atoms. There are a spread of Si–Si bond distances ranging from 2.39–2.46 Å. In the second Si+0.17- site, Si+0.17- is bonded in a 7-coordinate geometry to three K1+ and four Si+0.17- atoms. There are a spread of Si–Si bond distances ranging from 2.39–2.46 Å. In the third Si+0.17- site, Si+0.17- is bonded in a 7-coordinate geometry to three K1+ and four Si+0.17- atoms.
