Materials Data on Er(VGa2)2 by Materials Project
Er(VGa2)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er is bonded to twelve Ga atoms to form a mixture of distorted edge and face-sharing ErGa12 cuboctahedra. There are four shorter (2.83 Å) and eight longer (3.20 Å) Er–Ga bond lengths. V is bonded in a 10-coordinate geometry to two equivalent V and eight Ga atoms. Both V–V bond lengths are 2.62 Å. All V–Ga bond lengths are 2.72 Å. There are six inequivalent Ga sites. In the first Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Er, four equivalent V, and four equivalent Ga atoms. There are two shorter (2.61 Å) and two longer (2.79 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Er, four equivalent V, and four Ga atoms. There are two shorter (2.61 Å) and two longer (2.79 Å) Ga–Ga bond lengths. In the third Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Er, four equivalent V, and four Ga atoms. There are two shorter (2.61 Å) and two longer (2.79 Å) Ga–Ga bond lengths. In the fourth Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Er, four equivalent V, and four Ga atoms. There are two shorter (2.61 Å) and two longer (2.79 Å) Ga–Ga bond lengths. In the fifth Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Er, four equivalent V, and four Ga atoms. In the sixth Ga site, Ga is bonded in a 11-coordinate geometry to three equivalent Er, four equivalent V, and four Ga atoms.
