SrS3 crystallizes in the orthorhombic Aea2 space group. Sr(1) is bonded in a 9-coordinate geometry to three equivalent S(1) and six equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent S(2) atoms. In the second S site, S(2) is bonded to three equivalent Sr(1) and one S(1) atom to form a mixture of edge and corner-sharing SSr3S trigonal pyramids.
SrS3 crystallizes in the orthorhombic Aea2 space group. Sr(1) is bonded in a 9-coordinate geometry to three equivalent S(1) and six equivalent S(2) atoms. There is one shorter (3.36 Å) and two longer (3.47 Å) Sr(1)-S(1) bond lengths. There are a spread of Sr(1)-S(2) bond distances ranging from 3.01-3.07 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1) and two equivalent S(2) atoms. Both S(1)-S(2) bond lengths are 2.07 Å. In the second S site, S(2) is bonded to three equivalent Sr(1) and one S(1) atom to form a mixture of edge and corner-sharing SSr3S trigonal pyramids.
