The material structure described by SmAuAs2 crystallizes in the orthorhombic Cmce space group. Sm(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 Sm(1), four equivalent Au(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AuSm4As4Au4 cuboctahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent Au(1) atoms. In the second As site, As(2) is bonded in a 7-coordinate geometry to four equivalent Sm(1) and three equivalent As(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
