The structure described by RbCN2 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to one C(2), one N(3), two equivalent N(1), two equivalent N(2), and two equivalent N(4) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to one N(1), one N(2), two equivalent N(3), and two equivalent N(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. In the second C site, C(2) is bonded in a linear geometry to one Rb(1), one N(3), and one N(4) atom. There are four inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to one Rb(2), two equivalent Rb(1), and one C(1) atom. In the second N site, N(2) is bonded in a 1-coordinate geometry to one Rb(2), two equivalent Rb(1), and one C(1) atom. In the third N site, N(3) is bonded in a distorted single-bond geometry to one Rb(1), two equivalent Rb(2), and one C(2) atom. In the fourth N site, N(4) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one C(2) atom. is represented by the CIF card [CIF]
