The structure described by HgTl(AsS2)3 crystallizes in the monoclinic P2_1/c space group. Hg(1) is bonded in a distorted T-shaped geometry to one S(2), one S(5), and one S(6) atom. Tl(1) is bonded in a single-bond geometry to one S(6) atom. There are three inequivalent As sites. In the first As site, As(1) is bonded in a distorted T-shaped geometry to one S(3), one S(4), and one S(5) atom. In the second As site, As(2) is bonded in a distorted trigonal non-coplanar geometry to one S(1), one S(4), and one S(6) atom. In the third As site, As(3) is bonded in a distorted trigonal non-coplanar geometry to one S(1), one S(2), and one S(3) atom. There are six inequivalent S sites. In the first S site, S(5) is bonded in a water-like geometry to one Hg(1) and one As(1) atom. In the second S site, S(6) is bonded in a distorted trigonal non-coplanar geometry to one Hg(1), one Tl(1), and one As(2) atom. In the third S site, S(1) is bonded in an L-shaped geometry to one As(2) and one As(3) atom. In the fourth S site, S(2) is bonded in a water-like geometry to one Hg(1) and one As(3) atom. In the fifth S site, S(3) is bonded in a water-like geometry to one As(1) and one As(3) atom. In the sixth S site, S(4) is bonded in a water-like geometry to one As(1) and one As(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
