Materials Data on In4GeSe4 by Materials Project
Ge(InSe)4 is Hittorf-derived structured and crystallizes in the cubic Pa-3 space group. The structure is three-dimensional and consists of eight germanium molecules and one InSe framework. In the InSe framework, there are two inequivalent In1+ sites. In the first In1+ site, In1+ is bonded in a distorted T-shaped geometry to three Se2- atoms. There are a spread of In–Se bond distances ranging from 2.65–2.72 Å. In the second In1+ site, In1+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Se2- atoms. All In–Se bond lengths are 2.72 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent In1+ atoms. In the second Se2- site, Se2- is bonded in a trigonal non-coplanar geometry to three In1+ atoms.
