NdAgAs2 crystallizes in the orthorhombic Pnma space group. Nd(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 Nd(1), four equivalent Ag(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AgNd4Ag4As4 cuboctahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Nd(1) and four equivalent Ag(1) atoms. In the second As site, As(2) is bonded in a 6-coordinate geometry to four equivalent Nd(1) and two equivalent As(2) atoms.
NdAgAs2 crystallizes in the orthorhombic Pnma space group. Nd(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 Nd(1)-Ag(1) bond distances ranging from 3.52-3.54 Å. There are two shorter (3.03 Å) and two longer (3.04 Å) Nd(1)-As(1) bond lengths. There are a spread of Nd(1)-As(2) bond distances ranging from 3.09-3.24 Å. Ag(1) is bonded to four equivalent Nd(1), four equivalent Ag(1), and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing AgNd4Ag4As4 cuboctahedra. All Ag(1)-Ag(1) bond lengths are 2.87 Å. There are a spread of Ag(1)-As(1) bond distances ranging from 2.76-2.78 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to four equivalent Nd(1) and four equivalent Ag(1) atoms. In the second As site, As(2) is bonded in a 6-coordinate geometry to four equivalent Nd(1) and two equivalent As(2) atoms. Both As(2)-As(2) bond lengths are 2.59 Å.
