U2N2S crystallizes in the trigonal P-3m1 space group. U(1) is bonded in a 7-coordinate geometry to four equivalent N(1) and three equivalent S(1) atoms. N(1) is bonded to four equivalent U(1) atoms to form NU4 tetrahedra that share corners with six equivalent S(1)U6 octahedra, corners with six equivalent N(1)U4 tetrahedra, edges with three equivalent S(1)U6 octahedra, and edges with three equivalent N(1)U4 tetrahedra. The corner-sharing octahedral tilt angles range from 27-49°. S(1) is bonded to six equivalent U(1) atoms to form SU6 octahedra that share corners with twelve equivalent N(1)U4 tetrahedra, edges with six equivalent S(1)U6 octahedra, and edges with six equivalent N(1)U4 tetrahedra.
U2N2S crystallizes in the trigonal P-3m1 space group. U(1) is bonded in a 7-coordinate geometry to four equivalent N(1) and three equivalent S(1) atoms. There are three shorter (2.27 Å) and one longer (2.31 Å) U(1)-N(1) bond length. All U(1)-S(1) bond lengths are 2.93 Å. N(1) is bonded to four equivalent U(1) atoms to form NU4 tetrahedra that share corners with six equivalent S(1)U6 octahedra, corners with six equivalent N(1)U4 tetrahedra, edges with three equivalent S(1)U6 octahedra, and edges with three equivalent N(1)U4 tetrahedra.
