Materials Data on PrGa6 by Materials Project

PrGa6 crystallizes in the tetragonal P4/nbm space group. The structure is three-dimensional. Pr is bonded to twelve Ga atoms to form a mixture of distorted edge and face-sharing PrGa12 cuboctahedra. There are four shorter (3.18 Å) and eight longer (3.30 Å) Pr–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Pr and five Ga atoms. There are one shorter (2.50 Å) and four longer (2.63 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 4-coordinate geometry to one Pr and three Ga atoms. The Ga–Ga bond length is 2.50 Å.

Materials Data on PrGa6 by Materials Project

PrGa2(Ga)4 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Ga cluster and two PrGa2 clusters. In the Ga cluster, Ga is bonded in a 1-coordinate geometry to three equivalent Ga atoms. There are one shorter (2.53 Å) and two longer (2.72 Å) Ga–Ga bond lengths. In each PrGa2 cluster, Pr is bonded in a linear geometry to two equivalent Ga atoms. Both Pr–Ga bond lengths are 2.73 Å. Ga is bonded in a single-bond geometry to one Pr atom.
