EuAg4Sb2 crystallizes in the trigonal R-3m space group. Eu(1) is bonded to two equivalent Ag(1), six equivalent Ag(2), and six equivalent Sb(1) atoms to form distorted face-sharing EuAg8Sb6 octahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 11-coordinate geometry to one Eu(1), three equivalent Ag(1), three equivalent Ag(2), and four equivalent Sb(1) atoms. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent Eu(1), three equivalent Ag(1), and three equivalent Sb(1) atoms. Sb(1) is bonded in a 10-coordinate geometry to three equivalent Eu(1), three equivalent Ag(2), and four equivalent Ag(1) atoms.
EuAg4Sb2 crystallizes in the trigonal R-3m space group. Eu(1) is bonded to two equivalent Ag(1), six equivalent Ag(2), and six equivalent Sb(1) atoms to form distorted face-sharing EuAg8Sb6 octahedra. Both Eu(1)-Ag(1) bond lengths are 3.58 Å. All Eu(1)-Ag(2) bond lengths are 3.72 Å. All Eu(1)-Sb(1) bond lengths are 3.31 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 11-coordinate geometry to one Eu(1), three equivalent Ag(1), three equivalent Ag(2), and four equivalent Sb(1) atoms. All Ag(1)-Ag(1) bond lengths are 2.94 Å. All Ag(1)-Ag(2) bond lengths are 2.92 Å. There is one shorter (2.83 Å) and three longer (3.22 Å) Ag(1)-Sb(1) bond lengths. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to three equivalent Eu(1), three equivalent Ag(1), and three equivalent Sb(1) atoms. All Ag(2)-Sb(1) bond lengths are 2.80 Å. Sb(1) is bonded in a 10-coordinate geometry to three equivalent Eu(1), three equivalent Ag(2), and four equivalent Ag(1) atoms.
