Abstract

Sr2Si is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent Si4- atoms. There are one shorter (3.26 Å) and two longer (3.46 Å) Sr–Si bond lengths. In the second Sr2+ site, Sr2+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing SrSi4 tetrahedra. There are a spread of Sr–Si bond distances ranging from 3.18–3.25 Å. Si4- is bonded in a 7-coordinate geometry to seven Sr2+ atoms.
