Er(VGa2)2 crystallizes in the tetragonal I4/mmm space group. Er(1) is bonded to twelve Ga(1,1,1,1) atoms to form a mixture of distorted edge and face-sharing ErGa12 cuboctahedra. V(1) is bonded in a 10-coordinate geometry to two equivalent V(1) and eight Ga(1,1,1,1) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent V(1); and four Ga(1,1) atoms. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent V(1); and four Ga(1,1) atoms. In the third Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent V(1); and four Ga(1,1) atoms. In the fourth Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent V(1); and four Ga(1,1) atoms.
Er(VGa2)2 crystallizes in the tetragonal I4/mmm space group. Er(1) is bonded to twelve Ga(1,1,1,1) atoms to form a mixture of distorted edge and face-sharing ErGa12 cuboctahedra. There are four shorter (2.81 Å) and eight longer (3.17 Å) Er(1)-Ga(1,1,1,1) bond lengths. V(1) is bonded in a 10-coordinate geometry to two equivalent V(1) and eight Ga(1,1,1,1) atoms. Both V(1)-V(1) bond lengths are 2.59 Å. All V(1)-Ga(1,1,1,1) bond lengths are 2.70 Å. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent V(1); and four Ga(1,1) atoms. There are two shorter (2.58 Å) and two longer (2.78 Å) Ga(1)-Ga(1,1) bond lengths. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Er(1); four equivalent V(1); and four Ga(1,1) atoms. The Ga(1)-Ga(1) bond length is 2.58 Å.
