The compound described by Ru2Si is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a 4-coordinate geometry to five equivalent Si(1) atoms. In the second Ru site, Ru(1) is bonded in a 3-coordinate geometry to five equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to five equivalent Ru(1) and five equivalent Ru(2) atoms. is represented by the CIF card [CIF]
