Materials Data on CIN by Materials Project
CNI crystallizes in the trigonal R3m space group. The structure is one-dimensional and consists of three CNI ribbons oriented in the (0, 0, 1) direction. C4+ is bonded in a distorted linear geometry to one N3- and one I1- atom. The C–N bond length is 1.17 Å. The C–I bond length is 2.02 Å. N3- is bonded in a distorted linear geometry to one C4+ and one I1- atom. The N–I bond length is 2.68 Å. I1- is bonded in a linear geometry to one C4+ and one N3- atom.
