The material structure described by UCuBi2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. U(1) is bonded to four equivalent Cu(1), four equivalent Bi(1), and four equivalent Bi(2) atoms to form a mixture of distorted corner, face, and edge-sharing UCu4Bi8 cuboctahedra. Cu(1) is bonded in a distorted body-centered cubic geometry to four equivalent U(1) and four equivalent Bi(2) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Bi(1) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
