The structure described by SrB6(H3O4)2(BH)6 crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of eighteen hydridoboron(2.) (singlet) molecules and three SrB6(H3O4)2 clusters. In each SrB6(H3O4)2 cluster, Sr(1) is bonded in a distorted octahedral geometry to six equivalent O(2) atoms. B(2) is bonded in a single-bond geometry to one O(2) atom. H(2) is bonded in a distorted linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent H(2) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Sr(1), one B(2), and one H(2) atom. is represented by the CIF file [CIF]
