RbC2N2I3 crystallizes in the orthorhombic Pmmn space group. Rb(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent N(1) and two equivalent I(2) atoms. C(1) is bonded in a distorted linear geometry to one N(1) and one I(1) atom. N(1) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one C(1) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted single-bond geometry to one C(1) and one I(2) atom. In the second I site, I(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent I(1) atoms.
RbC2N2I3 crystallizes in the orthorhombic Pmmn space group. Rb(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent N(1) and two equivalent I(2) atoms. There are two shorter (3.05 Å) and two longer (3.19 Å) Rb(1)-N(1) bond lengths. Both Rb(1)-I(2) bond lengths are 3.98 Å. C(1) is bonded in a distorted linear geometry to one N(1) and one I(1) atom. The C(1)-N(1) bond length is 1.17 Å. The C(1)-I(1) bond length is 2.07 Å. N(1) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one C(1) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted single-bond geometry to one C(1) and one I(2) atom. The I(1)-I(2) bond length is 3.21 Å. In the second I site, I(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent I(1) atoms.
