The material structure described by TiCuSiAs 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 Cu(1), four equivalent Si(1), and four equivalent As(1) atoms. Cu(1) is bonded in a 12-coordinate geometry to four equivalent Ti(1), four equivalent Cu(1), and four equivalent As(1) atoms. Si(1) is bonded in a 8-coordinate geometry to four equivalent Ti(1) and four equivalent Si(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 file [CIF]
