Na(CrS2)2 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(1), two equivalent S(4), and three equivalent S(2) atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 49-54°. In the second Cr site, Cr(2) is bonded to one S(4), two equivalent S(1), and three equivalent S(3) atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles range from 49-54°. There are four inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Na(1), one Cr(1), and two equivalent Cr(2) atoms to form a mixture of distorted edge and corner-sharing SNa2Cr3 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent Na(1) and three equivalent Cr(1) atoms to form a mixture of distorted edge and corner-sharing SNa2Cr3 trigonal bipyramids. In the third S site, S(3) is bonded to two equivalent Na(1) and three equivalent Cr(2) atoms to form a mixture of edge and corner-sharing SNa2Cr3 square pyramids. In the fourth S site, S(4) is bonded in a 5-coordinate geometry to two equivalent Na(1), one Cr(2), and two equivalent Cr(1) atoms.
