The crystal structure described by TiCuGeAs is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. Ti(1) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four equivalent As(1) atoms. Cu(1) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Ge(1) atoms. As(1) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
