Materials Data on Na(SmS2)3 by Materials Project

SmNa(SmS2)2(S)2 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of four hydrogen sulfide molecules; two samario molecules; and one Na(SmS2)2 sheet oriented in the (0, 0, 1) direction. In the Na(SmS2)2 sheet, Na1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent S+1.33- atoms. All Na–S bond lengths are 2.79 Å. Sm+2.33+ is bonded in a linear geometry to two equivalent S+1.33- atoms. Both Sm–S bond lengths are 2.49 Å. S+1.33- is bonded in a distorted linear geometry to one Na1+ and one Sm+2.33+ atom.
