LiBH22(C2O)4 is alpha U structured and crystallizes in the orthorhombic Pbcn space group. The structure is zero-dimensional and consists of four LiBH22(C2O)4 clusters. Li(1) is bonded to two equivalent H(10), two equivalent O(1), and two equivalent O(2) atoms to form distorted LiH2O4 octahedra that share corners with two equivalent C(1)H3O tetrahedra and  an edgeedge with one B(1)H4 tetrahedra. Both Li(1)-H(10) bond lengths are 1.99 Å. Both Li(1)-O(1) bond lengths are 2.18 Å. Both Li(1)-O(2) bond lengths are 2.04 Å. B(1) is bonded to two equivalent H(10) and two equivalent H(11) atoms to form BH4 tetrahedra that share  an edgeedge with one Li(1)H2O4 octahedra. Both B(1)-H(10) bond lengths are 1.23 Å. Both B(1)-H(11) bond lengths are 1.23 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded to one H(1), one H(2), one H(3), and one O(2) atom to form CH3O tetrahedra that share  a cornercorner with one Li(1)H2O4 octahedra. The corner-sharing octahedral tilt angles are 55°. The C(1)-H(1) bond length is 1.10 Å. The C(1)-H(2) bond length is 1.10 Å. The C(1)-H(3) bond length is 1.09 Å. The C(1)-O(2) bond length is 1.43 Å. In the second C site, C(2) is bonded in a distorted trigonal non-coplanar geometry to one H(4), one H(5), and one O(1) atom. The C(2)-H(4) bond length is 1.10 Å. The C(2)-H(5) bond length is 1.10 Å. The C(2)-O(1) bond length is 1.44 Å. In the third C site, C(3) is bonded in a distorted trigonal non-coplanar geometry to one H(6), one H(7), and one O(1) atom. The C(3)-H(6) bond length is 1.11 Å. The C(3)-H(7) bond length is 1.10 Å. The C(3)-O(1) bond length is 1.43 Å. In the fourth C site, C(4) is bonded in a distorted trigonal non-coplanar geometry to one H(8), one H(9), and one O(2) atom. The C(4)-H(8) bond length is 1.11 Å. The C(4)-H(9) bond length is 1.10 Å. The C(4)-O(2) bond length is 1.44 Å. There are eleven inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom.

In the seventh H site, H(7) is bonded in a single-bond geometry to one C(3) atom. In the eighth H site, H(8) is bonded in a single-bond geometry to one C(4) atom. In the ninth H site, H(9) is bonded in a single-bond geometry to one C(4) atom. In the tenth H site, H(10) is bonded in an L-shaped geometry to one Li(1) and one B(1) atom. In the eleventh H site, H(11) is bonded in a single-bond geometry to one B(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one Li(1), one C(2), and one C(3) atom.
