CeAgAs2 is Parent of FeAs superconductors-derived structured and crystallizes in the orthorhombic Cmce space group. Ce(1) is bonded in a 8-coordinate geometry to four equivalent Ag(1), four equivalent As(1), and four equivalent As(2) atoms. Ag(1) is bonded to four equivalent Ce(1), four equivalent Ag(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AgCe4Ag4As4 cuboctahedra. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent As(2) atoms. In the second As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ag(1) atoms.

Ce(1) is bonded in a 8-coordinate geometry to four equivalent Ag(1), four equivalent As(1), and four equivalent As(2) atoms. There are two shorter (3.53 Å) and two longer (3.54 Å) Ce(1)-Ag(1) bond lengths. All Ce(1)-As(1) bond lengths are 3.04 Å. All Ce(1)-As(2) bond lengths are 3.11 Å. Ag(1) is bonded to four equivalent Ce(1), four equivalent Ag(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AgCe4Ag4As4 cuboctahedra. All Ag(1)-Ag(1) bond lengths are 2.87 Å. There are two shorter (2.76 Å) and two longer (2.78 Å) Ag(1)-As(1) bond lengths. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent As(2) atoms. There are a spread of As(2)-As(2) bond distances ranging from 2.82-2.92 Å. In the second As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ag(1) atoms.
