Materials Data on SrS3 by Materials Project
SrS3 crystallizes in the orthorhombic Aea2 space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine S+0.67- atoms. There are a spread of Sr–S bond distances ranging from 3.02–3.51 Å. There are two inequivalent S+0.67- sites. In the first S+0.67- site, S+0.67- is bonded in a 3-coordinate geometry to three equivalent Sr2+ and two equivalent S+0.67- atoms. Both S–S bond lengths are 2.09 Å. In the second S+0.67- site, S+0.67- is bonded to three equivalent Sr2+ and one S+0.67- atom to form a mixture of distorted corner and edge-sharing SSr3S trigonal pyramids.
