Materials Data on Ba4Ge23 by Materials Project
Abstract
Ba4Ge23 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. there are two inequivalent Ba sites. In the first Ba site, Ba is bonded in a 8-coordinate geometry to twenty Ge atoms. There are eight shorter (3.56 Å) and twelve longer (3.67 Å) Ba–Ge bond lengths. In the second Ba site, Ba is bonded in a 12-coordinate geometry to twelve Ge atoms. There are eight shorter (3.76 Å) and four longer (3.94 Å) Ba–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 5-coordinate geometry to one Ba and four Ge atoms. There are one shorter (2.53 Å) and three longer (2.58 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 7-coordinate geometry to three Ba and four Ge atoms. There are one shorter (2.60 Å) and one longer (2.65 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded to four equivalent Ba and four equivalent Ge atoms to form a mixture of distorted edge and corner-sharing GeBa4Ge4 tetrahedra.
