Materials Data on Na4Ga3Ge3B(HO3)4 by Materials Project

Na4Ga3(GeO4)3BH4 crystallizes in the cubic P-43n space group. The structure is three-dimensional and consists of two BH4 clusters and one Na4Ga3(GeO4)3 framework. In each BH4 cluster, B3- is bonded in a tetrahedral geometry to four equivalent H1+ atoms. All B–H bond lengths are 1.23 Å. H1+ is bonded in a single-bond geometry to one B3- atom. In the Na4Ga3(GeO4)3 framework, Na1+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. All Na–O bond lengths are 2.32 Å. Ga3+ is bonded to four equivalent O2- atoms to form GaO4 tetrahedra that share corners with four equivalent GeO4 tetrahedra. All Ga–O bond lengths are 1.86 Å. Ge+3.33+ is bonded to four equivalent O2- atoms to form GeO4 tetrahedra that share corners with four equivalent GaO4 tetrahedra. All Ge–O bond lengths are 1.77 Å. O2- is bonded in a trigonal planar geometry to one Na1+, one Ga3+, and one Ge+3.33+ atom.
