Rh5Co crystallizes in the triclinic P1 space group. There are five inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to two equivalent Rh(5) and one Co(1) atom. There is one shorter (2.53 Å) and one longer (2.86 Å) Rh(1)-Rh(5) bond length. The Rh(1)-Co(1) bond length is 1.67 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Rh(3) and one Rh(4) atom. The Rh(2)-Rh(3) bond length is 0.60 Å. The Rh(2)-Rh(4) bond length is 1.66 Å. In the third Rh site, Rh(3) is bonded in a single-bond geometry to one Rh(2), one Rh(4), and one Rh(5) atom. The Rh(3)-Rh(4) bond length is 1.72 Å. The Rh(3)-Rh(5) bond length is 2.57 Å. In the fourth Rh site, Rh(4) is bonded in a 5-coordinate geometry to one Rh(2), one Rh(3), one Rh(5), and two equivalent Co(1) atoms. The Rh(4)-Rh(5) bond length is 2.22 Å. There is one shorter (2.73 Å) and one longer (2.75 Å) Rh(4)-Co(1) bond length. In the fifth Rh site, Rh(5) is bonded in a 7-coordinate geometry to one Rh(3), one Rh(4), two equivalent Rh(1), two equivalent Rh(5), and one Co(1) atom. Both Rh(5)-Rh(5) bond lengths are 2.70 Å. The Rh(5)-Co(1) bond length is 3.00 Å. Co(1) is bonded in a distorted single-bond geometry to one Rh(1), one Rh(5), and two equivalent Rh(4) atoms.
