Sr(AsS2)2 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 7-coordinate geometry to one S(4), two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 3-coordinate geometry to one S(1), one S(2), one S(3), and one S(4) atom. In the second As site, As(2) is bonded in a trigonal non-coplanar geometry to one S(1), one S(3), and one S(4) atom. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1), one As(1), and one As(2) atom. In the second S site, S(2) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one As(1) atom. In the third S site, S(3) is bonded to two equivalent Sr(1), one As(1), and one As(2) atom to form distorted corner-sharing SSr2As2 trigonal pyramids. In the fourth S site, S(4) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1), one As(1), and one As(2) atom.
