The compound described by Rh4GaAs crystallizes in the orthorhombic Pmc2_1 space group. There are four inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to four equivalent Ga(1) and one As(1) atom. In the second Rh site, Rh(2) is bonded in a 3-coordinate geometry to one Ga(1) and two equivalent As(1) atoms. In the third Rh site, Rh(3) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent As(1) atoms. In the fourth Rh site, Rh(4) is bonded in a 4-coordinate geometry to three equivalent Ga(1) and two equivalent As(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to one Rh(2), two equivalent Rh(3), three equivalent Rh(4), and four equivalent Rh(1) atoms. As(1) is bonded in a 7-coordinate geometry to one Rh(1), two equivalent Rh(2), two equivalent Rh(3), and two equivalent Rh(4) atoms. is represented by the CIF file [CIF]
