The crystal structure described by LaCO crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 7-coordinate geometry to three equivalent C(1) and four equivalent O(1) atoms. C(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent La(1) and one C(1) atom. O(1) is bonded to four equivalent La(1) atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
