The compound described by Cr3Ru crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 2-coordinate geometry to two equivalent Cr(2) and two equivalent Ru(1) atoms. In the second Cr site, Cr(2) is bonded in a distorted body-centered cubic geometry to four equivalent Cr(1) and four equivalent Cr(2) atoms. Ru(1) is bonded in a 4-coordinate geometry to four equivalent Cr(1) atoms. is represented by the CIF card [CIF]
