La2C2N4O crystallizes in the monoclinic C2/c space group. La(1) is bonded in a 8-coordinate geometry to three equivalent N(1), three equivalent N(2), and two equivalent O(1) atoms. C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to three equivalent La(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to three equivalent La(1) and one C(1) atom. O(1) is bonded to four equivalent La(1) atoms to form edge-sharing OLa4 tetrahedra.
La2C2N4O crystallizes in the monoclinic C2/c space group. La(1) is bonded in a 8-coordinate geometry to three equivalent N(1), three equivalent N(2), and two equivalent O(1) atoms. There are a spread of La(1)-N(1) bond distances ranging from 2.60-2.77 Å. There are a spread of La(1)-N(2) bond distances ranging from 2.66-2.84 Å. There is one shorter (2.42 Å) and one longer (2.46 Å) La(1)-O(1) bond length. C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. The C(1)-N(1) bond length is 1.24 Å.
