RuIn3 crystallizes in the tetragonal P-4n2 space group. Ru(1) is bonded in a 8-coordinate geometry to two equivalent In(1) and six equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a linear geometry to two equivalent Ru(1) atoms. In the second In site, In(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms.
