LiC3N3H12Se is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two LiC3N3H12Se clusters. Li(1) is bonded in a 3-coordinate geometry to one N(1), one N(2), one N(3), and one Se(1) atom. The Li(1)-N(1) bond length is 2.05 Å. The Li(1)-N(2) bond length is 2.05 Å. The Li(1)-N(3) bond length is 2.05 Å. The Li(1)-Se(1) bond length is 2.66 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal non-coplanar geometry to one N(1), one H(3), and one H(4) atom. The C(1)-N(1) bond length is 1.47 Å. The C(1)-H(3) bond length is 1.10 Å.

The C(3)-N(3) bond length is 1.47 Å. The C(3)-H(11) bond length is 1.10 Å. The C(3)-H(12) bond length is 1.10 Å. There are three inequivalent N sites. In the first N site, N(1) is bonded to one Li(1), one C(1), one H(1), and one H(2) atom to form distorted corner-sharing NLiH2C tetrahedra. The N(1)-H(1) bond length is 1.03 Å. The N(1)-H(2) bond length is 1.03 Å. In the second N site, N(2) is bonded to one Li(1), one C(2), one H(5), and one H(6) atom to form distorted corner-sharing NLiH2C tetrahedra. The N(2)-H(5) bond length is 1.03 Å. The N(2)-H(6) bond length is 1.03 Å. In the third N site, N(3) is bonded to one Li(1), one C(3), one H(10), and one H(9) atom to form distorted corner-sharing NLiH2C tetrahedra. The N(3)-H(10) bond length is 1.04 Å. The N(3)-H(9) bond length is 1.02 Å. There are twelve inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(1) atom.

In the sixth H site, H(6) is bonded in a single-bond geometry to one N(2) atom. In the seventh H site, H(7) is bonded in a single-bond geometry to one C(2) atom. In the eighth H site, H(8) is bonded in a single-bond geometry to one C(2) atom. In the ninth H site, H(9) is bonded in a single-bond geometry to one N(3) atom. In the tenth H site, H(10) is bonded in a single-bond geometry to one N(3) atom. In the eleventh H site, H(11) is bonded in a single-bond geometry to one C(3) atom. In the twelfth H site, H(12) is bonded in a single-bond geometry to one C(3) atom. Se(1) is bonded in a distorted single-bond geometry to one Li(1) atom. Linkers: 3 NCCN. Metal clusters: 2 [Li].
