The crystal structure described by Ta3Ru crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 2-coordinate geometry to two equivalent Ta(2) and two equivalent Ru(1) atoms. In the second Ta site, Ta(2) is bonded in a distorted body-centered cubic geometry to four equivalent Ta(1) and four equivalent Ta(2) atoms. Ru(1) is bonded in a 4-coordinate geometry to four equivalent Ta(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
