UCo2Ge2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 16-coordinate geometry to four equivalent Co(1), four equivalent Co(2), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 4-coordinate geometry to four equivalent U(1) and four equivalent Ge(2) atoms. In the second Co site, Co(2) is bonded in a 5-coordinate geometry to four equivalent U(1), one Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to four equivalent U(1) and four equivalent Co(2) atoms. In the second Ge site, Ge(2) is bonded in a 5-coordinate geometry to four equivalent U(1), one Co(2), and four equivalent Co(1) atoms.
