Rh5Ga2As crystallizes in the orthorhombic Pbam space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to four equivalent Ga(1) and two equivalent As(1) atoms. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to four equivalent Ga(1) and one As(1) atom. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to four equivalent Ga(1) and two equivalent As(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to two equivalent Rh(3), four equivalent Rh(1), and four equivalent Rh(2) atoms. As(1) is bonded in a body-centered cubic geometry to two equivalent Rh(2), two equivalent Rh(3), and four equivalent Rh(1) atoms.
Rh5Ga2As crystallizes in the orthorhombic Pbam space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to four equivalent Ga(1) and two equivalent As(1) atoms. There are a spread of Rh(1)-Ga(1) bond distances ranging from 2.48-3.07 Å. Both Rh(1)-As(1) bond lengths are 2.45 Å. In the second Rh site, Rh(2) is bonded in a 5-coordinate geometry to four equivalent Ga(1) and one As(1) atom. There are two shorter (2.55 Å) and two longer (2.75 Å) Rh(2)-Ga(1) bond lengths. The Rh(2)-As(1) bond length is 2.40 Å. In the third Rh site, Rh(3) is bonded in a 6-coordinate geometry to four equivalent Ga(1) and two equivalent As(1) atoms. All Rh(3)-Ga(1) bond lengths are 2.60 Å. Both Rh(3)-As(1) bond lengths are 2.73 Å. Ga(1) is bonded in a 10-coordinate geometry to two equivalent Rh(3), four equivalent Rh(1), and four equivalent Rh(2) atoms. As(1) is bonded in a body-centered cubic geometry to two equivalent Rh(2), two equivalent Rh(3), and four equivalent Rh(1) atoms.
