The structure described by NaBH4 crystallizes in the tetragonal P-42_1c space group. Na(1) is bonded in a 12-coordinate geometry to twelve equivalent H(1) atoms. B(1) is bonded in a tetrahedral geometry to four equivalent H(1) atoms. H(1) is bonded in a distorted single-bond geometry to three equivalent Na(1) and one B(1) atom. is represented by the CIF file [CIF]
