The structure described by UCoNiGe2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 16-coordinate geometry to four equivalent Co(1), four equivalent Ni(1), four equivalent Ge(1), and four equivalent Ge(2) atoms. Co(1) is bonded in a 5-coordinate geometry to four equivalent U(1), one Ge(2), and four equivalent Ge(1) atoms. Ni(1) is bonded in a 4-coordinate geometry to four equivalent U(1) and four equivalent Ge(2) 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(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent U(1), one Co(1), and four equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
