Materials Data on SmFeP by Materials Project
SmFeP is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one SmFeP sheet oriented in the (0, 0, 1) direction. Sm is bonded in a 8-coordinate geometry to four equivalent Fe and four equivalent P atoms. All Sm–Fe bond lengths are 3.00 Å. All Sm–P bond lengths are 2.93 Å. Fe is bonded to four equivalent Sm and four equivalent P atoms to form a mixture of distorted edge and face-sharing FeSm4P4 tetrahedra. All Fe–P bond lengths are 2.25 Å. P is bonded in a 8-coordinate geometry to four equivalent Sm and four equivalent Fe atoms.
