The material structure described by SrTm2S4 crystallizes in the orthorhombic Pnma space group. Sr(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 Tm sites. In the first Tm site, Tm(1) is bonded to one S(3), two equivalent S(1), and three equivalent S(4) atoms to form a mixture of edge and corner-sharing TmS6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. In the second Tm site, Tm(2) is bonded to one S(1), two equivalent S(3), and three equivalent S(2) atoms to form a mixture of edge and corner-sharing TmS6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. There are four inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Sr(1), one Tm(2), and two equivalent Tm(1) atoms to form a mixture of distorted edge and corner-sharing SSr2Tm3 trigonal bipyramids. In the second S site, S(2) is bonded to two equivalent Sr(1) and three equivalent Tm(2) atoms to form a mixture of edge and corner-sharing SSr2Tm3 square pyramids. In the third S site, S(3) is bonded to two equivalent Sr(1), one Tm(1), and two equivalent Tm(2) atoms to form a mixture of distorted edge and corner-sharing SSr2Tm3 trigonal bipyramids. In the fourth S site, S(4) is bonded to two equivalent Sr(1) and three equivalent Tm(1) atoms to form a mixture of distorted edge and corner-sharing SSr2Tm3 trigonal bipyramids. is represented by the CIF file [CIF]
