Materials Data on RbC2I3N2 by Materials Project
RbC2N2I3 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Rb1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent N3- and two equivalent I1- atoms. There are two shorter (3.05 Å) and two longer (3.19 Å) Rb–N bond lengths. Both Rb–I bond lengths are 3.98 Å. 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 2.07 Å. N3- is bonded in a 1-coordinate geometry to two equivalent Rb1+ and one C4+ atom. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted single-bond geometry to one C4+ and one I1- atom. The I–I bond length is 3.21 Å. In the second I1- site, I1- is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two equivalent I1- atoms.
