Materials Data on Er3Co by Materials Project
Er3Co is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Er3Co sheets oriented in the (0, 0, 1) direction. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 2-coordinate geometry to two equivalent Co atoms. There are one shorter (2.71 Å) and one longer (2.79 Å) Er–Co bond lengths. In the second Er site, Er is bonded in a distorted bent 150 degrees geometry to two equivalent Co atoms. There are one shorter (2.65 Å) and one longer (2.76 Å) Er–Co bond lengths. Co is bonded in a 6-coordinate geometry to six Er atoms.
