The structure described by Th2AsNO crystallizes in the trigonal P3m1 space group. There are two inequivalent Th sites. In the first Th site, Th(1) is bonded in a 7-coordinate geometry to three equivalent As(1), one N(1), and three equivalent O(1) atoms. In the second Th site, Th(2) is bonded in a 7-coordinate geometry to three equivalent As(1), three equivalent N(1), and one O(1) atom. As(1) is bonded to three equivalent Th(1) and three equivalent Th(2) atoms to form AsTh6 octahedra that share corners with six equivalent N(1)Th4 tetrahedra, corners with six equivalent O(1)Th4 tetrahedra, edges with six equivalent As(1)Th6 octahedra, edges with three equivalent N(1)Th4 tetrahedra, and edges with three equivalent O(1)Th4 tetrahedra. N(1) is bonded to one Th(1) and three equivalent Th(2) atoms to form NTh4 tetrahedra that share corners with six equivalent As(1)Th6 octahedra, corners with six equivalent N(1)Th4 tetrahedra, edges with three equivalent As(1)Th6 octahedra, and edges with three equivalent O(1)Th4 tetrahedra. The corner-sharing octahedral tilt angles range from 24-50°. O(1) is bonded to one Th(2) and three equivalent Th(1) atoms to form OTh4 tetrahedra that share corners with six equivalent As(1)Th6 octahedra, corners with six equivalent O(1)Th4 tetrahedra, edges with three equivalent As(1)Th6 octahedra, and edges with three equivalent N(1)Th4 tetrahedra. The corner-sharing octahedral tilt angles range from 25-49°. is represented by the CIF file [CIF]
