Materials Data on Tb3Co by Materials Project
Tb3Co is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Tb3Co sheets oriented in the (0, 0, 1) direction. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 2-coordinate geometry to two equivalent Co atoms. There are one shorter (2.74 Å) and one longer (2.87 Å) Tb–Co bond lengths. In the second Tb site, Tb is bonded in a distorted bent 150 degrees geometry to two equivalent Co atoms. There are one shorter (2.67 Å) and one longer (2.83 Å) Tb–Co bond lengths. Co is bonded in a 6-coordinate geometry to six Tb atoms.
