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.
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. There are two shorter (2.83 Å) and one longer (2.87 Å) La(1)-C(1) bond length. There are two shorter (2.41 Å) and two longer (2.43 Å) La(1)-O(1) bond lengths. C(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent La(1) and one C(1) atom. The C(1)-C(1) bond length is 1.26 Å. O(1) is bonded to four equivalent La(1) atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra.
