CeOC crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent O(1) atoms. C(1) is bonded to four equivalent Ce(1) and one C(1) atom to form distorted CCe4C trigonal bipyramids that share corners with ten equivalent O(1)Ce4 tetrahedra, corners with six equivalent C(1)Ce4C trigonal bipyramids, edges with three equivalent O(1)Ce4 tetrahedra, and edges with three equivalent C(1)Ce4C trigonal bipyramids. O(1) is bonded to four equivalent Ce(1) atoms to form OCe4 tetrahedra that share corners with six equivalent O(1)Ce4 tetrahedra, corners with ten equivalent C(1)Ce4C trigonal bipyramids, edges with three equivalent O(1)Ce4 tetrahedra, and edges with three equivalent C(1)Ce4C trigonal bipyramids.
CeOC crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent O(1) atoms. There are a spread of Ce(1)-C(1) bond distances ranging from 2.64-2.73 Å. There are three shorter (2.36 Å) and one longer (2.38 Å) Ce(1)-O(1) bond length. C(1) is bonded to four equivalent Ce(1) and one C(1) atom to form distorted CCe4C trigonal bipyramids that share corners with ten equivalent O(1)Ce4 tetrahedra, corners with six equivalent C(1)Ce4C trigonal bipyramids, edges with three equivalent O(1)Ce4 tetrahedra, and edges with three equivalent C(1)Ce4C trigonal bipyramids. The C(1)-C(1) bond length is 1.29 Å. O(1) is bonded to four equivalent Ce(1) atoms to form OCe4 tetrahedra that share corners with six equivalent O(1)Ce4 tetrahedra, corners with ten equivalent C(1)Ce4C trigonal bipyramids, edges with three equivalent O(1)Ce4 tetrahedra, and edges with three equivalent C(1)Ce4C trigonal bipyramids.
