SmAgAs2 is Parent of FeAs superconductors-derived structured and crystallizes in the orthorhombic Pnma space group. Sm(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 Sm(1), four equivalent Ag(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AgSm4Ag4As4 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 Ag(1) atoms. In the second As site, As(2) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent As(2) atoms.
SmAgAs2 is Parent of FeAs superconductors-derived structured and crystallizes in the orthorhombic Pnma space group. Sm(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 a spread of Sm(1)-Ag(1) bond distances ranging from 3.47-3.49 Å. There are two shorter (2.98 Å) and two longer (2.99 Å) Sm(1)-As(1) bond lengths. There is one shorter (3.10 Å) and three longer (3.12 Å) Sm(1)-As(2) bond lengths. Ag(1) is bonded to four equivalent Sm(1), four equivalent Ag(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AgSm4Ag4As4 cuboctahedra. All Ag(1)-Ag(1) bond lengths are 2.82 Å. There are a spread of Ag(1)-As(1) bond distances ranging from 2.73-2.75 Å. 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 Ag(1) atoms. In the second As site, As(2) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent As(2) atoms. There are two shorter (2.71 Å) and two longer (2.94 Å) As(2)-As(2) bond lengths.
