Materials Data on GeH4 by Materials Project
GeH4 is Silicon tetrafluoride-like structured and crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of four germane molecules. Ge2+ is bonded in a tetrahedral geometry to four H+0.50- atoms. There is two shorter (1.53 Å) and two longer (1.54 Å) Ge–H bond length. There are four inequivalent H+0.50- sites. In the first H+0.50- site, H+0.50- is bonded in a single-bond geometry to one Ge2+ atom. In the second H+0.50- site, H+0.50- is bonded in a single-bond geometry to one Ge2+ atom. In the third H+0.50- site, H+0.50- is bonded in a single-bond geometry to one Ge2+ atom. In the fourth H+0.50- site, H+0.50- is bonded in a single-bond geometry to one Ge2+ atom.
