CsNaC2 crystallizes in the orthorhombic Pbcm space group. Cs(1) is bonded in a 5-coordinate geometry to one C(2) and four equivalent C(1) atoms. Na(1) is bonded in a 6-coordinate geometry to two equivalent C(1) and four equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 7-coordinate geometry to four equivalent Cs(1), two equivalent Na(1), and one C(2) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to one Cs(1), four equivalent Na(1), and one C(1) atom.
