BaSn2S5 crystallizes in the orthorhombic Pccn space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent S(3), four equivalent S(1), and four equivalent S(2) atoms. Sn(1) is bonded to one S(3), two equivalent S(1), and two equivalent S(2) atoms to form a mixture of corner and edge-sharing SnS5 trigonal bipyramids. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ba(1) and two equivalent Sn(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ba(1) and two equivalent Sn(1) atoms. In the third S site, S(3) is bonded in a distorted see-saw-like geometry to two equivalent Ba(1) and two equivalent Sn(1) atoms.
BaSn2S5 crystallizes in the orthorhombic Pccn space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent S(3), four equivalent S(1), and four equivalent S(2) atoms. Both Ba(1)-S(3) bond lengths are 3.40 Å. There are two shorter (3.24 Å) and two longer (3.52 Å) Ba(1)-S(1) bond lengths. There are two shorter (3.33 Å) and two longer (3.59 Å) Ba(1)-S(2) bond lengths. Sn(1) is bonded to one S(3), two equivalent S(1), and two equivalent S(2) atoms to form a mixture of corner and edge-sharing SnS5 trigonal bipyramids. The Sn(1)-S(3) bond length is 2.50 Å. There is one shorter (2.45 Å) and one longer (2.55 Å) Sn(1)-S(1) bond length. There is one shorter (2.44 Å) and one longer (2.61 Å) Sn(1)-S(2) bond length. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ba(1) and two equivalent Sn(1) atoms.
