Materials Data on CoI7N6 by Materials Project

Co(IN1)2(IN2)2(I)3 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two cobalt molecules; four jodamin molecules; four IN2 clusters; and two I ribbons oriented in the (0, 1, 0) direction. In each IN2 cluster, N+0.67+ is bonded in a distorted single-bond geometry to one I1- atom. The N–I bond length is 2.02 Å. I1- is bonded in a distorted L-shaped geometry to two equivalent N+0.67+ atoms. In each I ribbon, there are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 8-coordinate geometry to four equivalent I1- atoms. All I–I bond lengths are 3.25 Å. In the second I1- site, I1- is bonded in a 2-coordinate geometry to two equivalent I1- atoms.
