The structure described by UCuAs2 crystallizes in the tetragonal P4/nmm space group. U(1) is bonded in a 6-coordinate geometry to four equivalent Cu(1), two equivalent As(1), and four equivalent As(2) atoms. Cu(1) is bonded in a 10-coordinate geometry to four equivalent U(1), two equivalent As(2), and four equivalent As(1) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to two equivalent U(1) and four equivalent Cu(1) atoms. In the second As site, As(2) is bonded in a 6-coordinate geometry to four equivalent U(1) and two equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
