Sc3Rh5B2 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 13-coordinate geometry to two equivalent Rh(2), eight equivalent Rh(1), and three equivalent B(1) atoms. In the second Sc site, Sc(2) is bonded in a body-centered cubic geometry to eight equivalent Rh(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to two equivalent Sc(2), four equivalent Sc(1), and two equivalent B(1) atoms. In the second Rh site, Rh(2) is bonded in a distorted body-centered cubic geometry to four equivalent Sc(1) and four equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1), two equivalent Rh(2), and four equivalent Rh(1) atoms.

In the first Sc site, Sc(1) is bonded in a 13-coordinate geometry to two equivalent Rh(2), eight equivalent Rh(1), and three equivalent B(1) atoms. Both Sc(1)-Rh(2) bond lengths are 2.80 Å. There are four shorter (2.89 Å) and four longer (2.96 Å) Sc(1)-Rh(1) bond lengths. There is one shorter (2.70 Å) and two longer (2.86 Å) Sc(1)-B(1) bond lengths. In the second Sc site, Sc(2) is bonded in a body-centered cubic geometry to eight equivalent Rh(1) atoms. All Sc(2)-Rh(1) bond lengths are 2.70 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to two equivalent Sc(2), four equivalent Sc(1), and two equivalent B(1) atoms. Both Rh(1)-B(1) bond lengths are 2.18 Å. In the second Rh site, Rh(2) is bonded in a distorted body-centered cubic geometry to four equivalent Sc(1) and four equivalent B(1) atoms. All Rh(2)-B(1) bond lengths are 2.26 Å. B(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1), two equivalent Rh(2), and four equivalent Rh(1) atoms.
