The crystal structure described by SmCoSi4 crystallizes in the hexagonal P6/mmm space group. Sm(1) is bonded in a 14-coordinate geometry to two equivalent Co(1) and twelve equivalent Si(1) atoms. Co(1) is bonded in a 14-coordinate geometry to two equivalent Sm(1) and twelve equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to three equivalent Sm(1), three equivalent Co(1), and four equivalent Si(1) atoms. is represented by the CIF file [CIF]
