Materials Data on Pr3Ru by Materials Project
Pr3Ru is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Pr3Ru sheets oriented in the (0, 0, 1) direction. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 2-coordinate geometry to two equivalent Ru atoms. There are one shorter (2.92 Å) and one longer (2.98 Å) Pr–Ru bond lengths. In the second Pr site, Pr is bonded in a bent 150 degrees geometry to two equivalent Ru atoms. There are one shorter (2.87 Å) and one longer (2.90 Å) Pr–Ru bond lengths. Ru is bonded in a 6-coordinate geometry to six Pr atoms.
