RuSi3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Ru(1) is bonded in a distorted body-centered cubic geometry to six equivalent Si(2) and eight equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ru(1) and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 14-coordinate geometry to six equivalent Ru(1) and eight equivalent Si(1) atoms.
