The crystal structure described by La3Co is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 2-coordinate geometry to three equivalent Co(1) atoms. In the second La site, La(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Co(1) atoms. Co(1) is bonded in a 8-coordinate geometry to two equivalent La(2) and six equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
