The material described by C4H12Se(NO)2 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four C4H12Se(NO)2 clusters. There are two inequivalent C sites. In the first C site, C(1) is bonded to one N(1), one H(1), one H(2), and one H(3) atom to form CH3N tetrahedra that share  a cornercorner with one C(2)H3N tetrahedra and  a cornercorner with one Se(1)N2O2 tetrahedra. In the second C site, C(2) is bonded to one N(1), one H(4), one H(5), and one H(6) atom to form CH3N tetrahedra that share  a cornercorner with one C(1)H3N tetrahedra and  a cornercorner with one Se(1)N2O2 tetrahedra. N(1) is bonded in a trigonal non-coplanar geometry to one C(1), one C(2), and one Se(1) atom. There are six 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 fifth H site, H(5) is bonded in a single-bond geometry to one C(2) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one C(2) atom. Se(1) is bonded to two equivalent N(1) and two equivalent O(1) atoms to form SeN2O2 tetrahedra that share corners with two equivalent C(1)H3N tetrahedra and corners with two equivalent C(2)H3N tetrahedra. O(1) is bonded in a single-bond geometry to one Se(1) atom. is represented by the CIF file [CIF]
