The crystal structure described by KCN5H2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent N(2), two equivalent N(3), and two equivalent N(5) atoms. C(1) is bonded in a trigonal planar geometry to one N(1), one N(3), and one N(4) atom. There are five inequivalent N sites. In the first N site, N(5) is bonded in a distorted see-saw-like geometry to two equivalent K(1), one N(1), and one N(2) atom. In the second N site, N(1) is bonded in a distorted single-bond geometry to two equivalent K(1), one C(1), and one N(5) atom. In the third N site, N(2) is bonded in a 4-coordinate geometry to two equivalent K(1), one N(3), and one N(5) atom. In the fourth N site, N(3) is bonded in a distorted single-bond geometry to two equivalent K(1), one C(1), and one N(2) atom. In the fifth N site, N(4) is bonded in a trigonal non-coplanar geometry to one C(1), one H(1), and one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(4) atom. is represented by the CIF file [CIF]
