Sr2Re6S11 crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a 10-coordinate geometry to one S(3), three equivalent S(2), and six equivalent S(1) atoms. Re(1) is bonded to one S(2), one S(3), and three equivalent S(1) atoms to form a mixture of corner and edge-sharing ReS5 square pyramids. There are three inequivalent S sites. In the first S site, S(3) is bonded in a 4-coordinate geometry to one Sr(1) and three equivalent Re(1) atoms. In the second S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Sr(1) and three equivalent Re(1) atoms. In the third S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Sr(1) and two equivalent Re(1) atoms.
Sr2Re6S11 crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a 10-coordinate geometry to one S(3), three equivalent S(2), and six equivalent S(1) atoms. The Sr(1)-S(3) bond length is 3.08 Å. All Sr(1)-S(2) bond lengths are 3.03 Å. There are three shorter (3.33 Å) and three longer (3.55 Å) Sr(1)-S(1) bond lengths. Re(1) is bonded to one S(2), one S(3), and three equivalent S(1) atoms to form a mixture of corner and edge-sharing ReS5 square pyramids. The Re(1)-S(2) bond length is 2.50 Å. The Re(1)-S(3) bond length is 2.38 Å. There are a spread of Re(1)-S(1) bond distances ranging from 2.41-2.43 Å. There are three inequivalent S sites.
