Nb In In In S
NbIn3S is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. Nb(1) is bonded to twelve equivalent In(1) atoms to form distorted NbIn12 cuboctahedra that share corners with twelve equivalent Nb(1)In12 cuboctahedra, faces with six equivalent Nb(1)In12 cuboctahedra, and faces with eight equivalent S(1)In6 octahedra. There are a spread of Nb(1)-In(1) bond distances ranging from 3.36-3.79 Å. In(1) is bonded in a distorted linear geometry to four equivalent Nb(1) and two equivalent S(1) atoms. There is one shorter (2.38 Å) and one longer (2.68 Å) In(1)-S(1) bond length. S(1) is bonded to six equivalent In(1) atoms to form SIn6 octahedra that share corners with six equivalent S(1)In6 octahedra and faces with eight equivalent Nb(1)In12 cuboctahedra. The corner-sharing octahedra are not tilted.
