The material structure described by SmCo2B2 crystallizes in the tetragonal I4/mmm space group. Sm(1) is bonded in a 16-coordinate geometry to eight equivalent Co(1) and eight equivalent B(1) atoms. Co(1) is bonded in a 4-coordinate geometry to four equivalent Sm(1) and four equivalent B(1) atoms. B(1) is bonded in a 4-coordinate geometry to four equivalent Sm(1) and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
