LuCuAs2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Lu(1) is bonded in a 8-coordinate geometry to four equivalent As(1) and four equivalent As(2) atoms. Cu(1) is bonded to four equivalent As(2) atoms to form a mixture of distorted edge and corner-sharing CuAs4 tetrahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Lu(1) and four equivalent As(1) atoms. In the second As site, As(2) is bonded in a 8-coordinate geometry to four equivalent Lu(1) and four equivalent Cu(1) atoms.
