SrSiO3 crystallizes in the monoclinic Pc space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(2), and two equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a 7-coordinate geometry to one O(2), one O(4), one O(6), two equivalent O(1), and two equivalent O(5) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a water-like geometry to one O(1) and one O(2) atom. In the second Si site, Si(2) is bonded in a distorted tetrahedral geometry to one O(3), one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites.
