Materials Data on La3Co by Materials Project
La3Co is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two La3Co sheets oriented in the (0, 0, 1) direction. there are two inequivalent La sites. In the first La site, La is bonded in a distorted water-like geometry to two equivalent Co atoms. There are one shorter (2.78 Å) and one longer (2.92 Å) La–Co bond lengths. In the second La site, La is bonded in a bent 150 degrees geometry to two equivalent Co atoms. There are one shorter (2.70 Å) and one longer (2.97 Å) La–Co bond lengths. Co is bonded in a 6-coordinate geometry to six La atoms.
