RuGa3 crystallizes in the tetragonal P4_2/mnm space group. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ga(2) and six equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. In the second Ga site, Ga(2) is bonded in a linear geometry to two equivalent Ru(1) atoms.
RuGa3 crystallizes in the tetragonal P4_2/mnm space group. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Ga(2) and six equivalent Ga(1) atoms. Both Ru(1)-Ga(2) bond lengths are 2.43 Å. There are two shorter (2.47 Å) and four longer (2.57 Å) Ru(1)-Ga(1) bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. In the second Ga site, Ga(2) is bonded in a linear geometry to two equivalent Ru(1) atoms.
