Na2PtS2 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1), three equivalent S(1), and three equivalent S(2) atoms. In the second Na site, Na(2) is bonded in a 7-coordinate geometry to two equivalent Pt(1), two equivalent S(1), and three equivalent S(2) atoms. Pt(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), two equivalent Na(2), two equivalent S(1), and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 7-coordinate geometry to two equivalent Na(2), three equivalent Na(1), and two equivalent Pt(1) atoms. In the second S site, S(2) is bonded in a 8-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and two equivalent Pt(1) atoms.
