CeAuAs2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Ce(1) is bonded in a 12-coordinate geometry to four equivalent Au(1), four equivalent As(1), and four equivalent As(2) atoms. Au(1) is bonded to four equivalent Ce(1), four equivalent Au(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AuCe4As4Au4 cuboctahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Au(1) atoms. In the second As site, As(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent As(2) atoms.
