Th2N2O crystallizes in the trigonal P-3m1 space group. Th(1) is bonded in a 7-coordinate geometry to four equivalent N(1) and three equivalent O(1) atoms. N(1) is bonded to four equivalent Th(1) atoms to form NTh4 tetrahedra that share corners with six equivalent O(1)Th6 octahedra, corners with six equivalent N(1)Th4 tetrahedra, edges with three equivalent O(1)Th6 octahedra, and edges with three equivalent N(1)Th4 tetrahedra. The corner-sharing octahedral tilt angles range from 19-57°. O(1) is bonded to six equivalent Th(1) atoms to form OTh6 octahedra that share corners with twelve equivalent N(1)Th4 tetrahedra, edges with six equivalent O(1)Th6 octahedra, and edges with six equivalent N(1)Th4 tetrahedra.
Th2N2O crystallizes in the trigonal P-3m1 space group. Th(1) is bonded in a 7-coordinate geometry to four equivalent N(1) and three equivalent O(1) atoms. There are three shorter (2.35 Å) and one longer (2.38 Å) Th(1)-N(1) bond length. All Th(1)-O(1) bond lengths are 2.73 Å. N(1) is bonded to four equivalent Th(1) atoms to form NTh4 tetrahedra that share corners with six equivalent O(1)Th6 octahedra, corners with six equivalent N(1)Th4 tetrahedra, edges with three equivalent O(1)Th6 octahedra, and edges with three equivalent N(1)Th4 tetrahedra. The corner-sharing octahedral tilt angles range from 19-57°. O(1) is bonded to six equivalent Th(1) atoms to form OTh6 octahedra that share corners with twelve equivalent N(1)Th4 tetrahedra, edges with six equivalent O(1)Th6 octahedra, and edges with six equivalent N(1)Th4 tetrahedra.
