CdCN2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cd2+ is bonded to six equivalent N3- atoms to form edge-sharing CdN6 octahedra. All Cd–N bond lengths are 2.41 Å. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.24 Å. N3- is bonded in a 4-coordinate geometry to three equivalent Cd2+ and one C4+ atom.
CdCN2 crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three hydrogen cyanide molecules and three CdN sheets oriented in the (0, 0, 1) direction. In each CdN sheet, Cd2+ is bonded in a trigonal non-coplanar geometry to three equivalent N3- atoms. All Cd–N bond lengths are 2.27 Å. N3- is bonded in a trigonal non-coplanar geometry to three equivalent Cd2+ atoms.
CdCN2 crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three methane molecules; three Cd sheets oriented in the (0, 0, 1) direction; and three N2 sheets oriented in the (0, 0, 1) direction. In each Cd sheet, Cd2+ is bonded in a hexagonal planar geometry to six equivalent Cd2+ atoms. All Cd–Cd bond lengths are 2.54 Å. In each N2 sheet, N3- is bonded in a distorted trigonal non-coplanar geometry to three equivalent N3- atoms. All N–N bond lengths are 1.64 Å.
CdCN2 crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three hydrogen cyanide molecules and three CdN clusters. In each CdN cluster, Cd2+ is bonded in a distorted single-bond geometry to one N3- atom. The Cd–N bond length is 2.13 Å. N3- is bonded in a single-bond geometry to one Cd2+ atom.
