UThCo2 crystallizes in the trigonal R3m space group. U(1) is bonded in a 11-coordinate geometry to four equivalent Th(1), three equivalent Co(2), and four equivalent Co(1) atoms. There are three shorter (2.72 Å) and one longer (3.54 Å) U(1)-Th(1) bond length. All U(1)-Co(2) bond lengths are 2.71 Å. There are three shorter (2.71 Å) and one longer (3.96 Å) U(1)-Co(1) bond length. Th(1) is bonded in a single-bond geometry to four equivalent U(1), one Co(2), and three equivalent Co(1) atoms. The Th(1)-Co(2) bond length is 0.43 Å. All Th(1)-Co(1) bond lengths are 2.71 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 6-coordinate geometry to four equivalent U(1) and three equivalent Th(1) atoms. In the second Co site, Co(2) is bonded in a single-bond geometry to three equivalent U(1) and one Th(1) atom.
