Materials Data on VSiGe by Materials Project
V(SiGe) crystallizes in the trigonal P3_212 space group. The structure is three-dimensional. V2+ is bonded in a 7-coordinate geometry to two equivalent Ge2+ and five equivalent Si4- atoms. Both V–Ge bond lengths are 2.57 Å. There are two shorter (2.56 Å) and three longer (2.71 Å) V–Si bond lengths. Ge2+ is bonded in a 7-coordinate geometry to two equivalent V2+ and five equivalent Si4- atoms. There are a spread of Ge–Si bond distances ranging from 2.55–2.73 Å. Si4- is bonded in a 10-coordinate geometry to five equivalent V2+ and five equivalent Ge2+ atoms.
