The compound described by Ru4Si3 crystallizes in the orthorhombic Pnma space group. There are four inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 3-coordinate geometry to one Si(1) and four equivalent Si(3) atoms. In the second Ru site, Ru(2) is bonded in a 7-coordinate geometry to two equivalent Si(1), two equivalent Si(3), and three equivalent Si(2) atoms. In the third Ru site, Ru(3) is bonded in a 8-coordinate geometry to one Si(3), three equivalent Si(1), and four equivalent Si(2) atoms. In the fourth Ru site, Ru(4) is bonded in a 6-coordinate geometry to one Si(2), two equivalent Si(1), and three equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a body-centered cubic geometry to one Ru(1), two equivalent Ru(2), two equivalent Ru(4), and three equivalent Ru(3) atoms. In the second Si site, Si(2) is bonded in a distorted body-centered cubic geometry to one Ru(4), three equivalent Ru(2), and four equivalent Ru(3) atoms. In the third Si site, Si(3) is bonded in a 10-coordinate geometry to one Ru(3), two equivalent Ru(2), three equivalent Ru(4), and four equivalent Ru(1) atoms. is represented by the CIF card [CIF]
