The crystal structure described by La2Co2Si crystallizes in the triclinic P-1 space group. La(1) is bonded in a 10-coordinate geometry to six equivalent Co(1) and four equivalent Si(1) atoms. Co(1) is bonded in a 9-coordinate geometry to six equivalent La(1), two equivalent Co(1), and one Si(1) atom. Si(1) is bonded in a distorted q6 geometry to eight equivalent La(1) and two equivalent Co(1) atoms. is represented by the CIF file [CIF]
