Materials Data on Sm3Co by Materials Project
Abstract
Sm3Co is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Sm3Co sheets oriented in the (0, 0, 1) direction. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a bent 150 degrees geometry to two equivalent Co atoms. There are one shorter (2.73 Å) and one longer (2.85 Å) Sm–Co bond lengths. In the second Sm site, Sm is bonded in a distorted water-like geometry to two equivalent Co atoms. There are one shorter (2.78 Å) and one longer (2.88 Å) Sm–Co bond lengths. Co is bonded in a 6-coordinate geometry to six Sm atoms.
