The structure described by SmCoSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Sm(1) is bonded in a 9-coordinate geometry to four equivalent Co(1) and five equivalent Si(1) atoms. Co(1) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent Sm(1) and four equivalent Co(1) atoms. is represented by the CIF file [CIF]
