Rb2Pt(CN)4 crystallizes in the orthorhombic Imma space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 16-coordinate geometry to four equivalent C(1), four equivalent C(2), four equivalent N(1), and four equivalent N(2) atoms. In the second Rb site, Rb(2) is bonded in a distorted body-centered cubic geometry to four equivalent N(1) and four equivalent N(2) atoms. Pt(1) is bonded in a square co-planar geometry to two equivalent C(1) and two equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to two equivalent Rb(1), one Pt(1), and one N(1) atom. In the second C site, C(2) is bonded in a distorted linear geometry to two equivalent Rb(1), one Pt(1), and one N(2) atom. There are two inequivalent N sites. In the first N site, N(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one C(2) atom. In the second N site, N(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1), two equivalent Rb(2), and one C(1) atom.
