The compound described by Na(CrS2)2 crystallizes in the monoclinic P2/m space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form edge-sharing CrS6 octahedra. In the second Cr site, Cr(2) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form edge-sharing CrS6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Na(1), one Cr(2), and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded to two equivalent Na(1), one Cr(1), and two equivalent Cr(2) atoms to form a mixture of distorted corner and edge-sharing SNa2Cr3 trigonal bipyramids. is represented by the CIF file [CIF]
