SrSi2 crystallizes in the cubic P4_132 space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to eight Si(1,1,1) atoms. In the second Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to eight Si(1,1,1) atoms. In the third Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to eight Si(1,1,1) atoms. In the fourth Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to eight Si(1,1,1) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 7-coordinate geometry to four Sr(1,1,1,1) and three Si(1,1) atoms. In the second Si site, Si(1) is bonded in a 7-coordinate geometry to four Sr(1,1,1,1) and three Si(1,1) atoms. In the third Si site, Si(1) is bonded in a 7-coordinate geometry to four Sr(1,1,1,1) and three Si(1,1) atoms.
SrSi2 crystallizes in the cubic P4_132 space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to eight Si(1,1,1) atoms. There are six shorter (3.27 Å) and two longer (3.38 Å) Sr(1)-Si(1,1,1) bond lengths. In the second Sr site, Sr(1) is bonded in a distorted body-centered cubic geometry to eight Si(1,1,1) atoms.
