MnIn3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Mn(1) is bonded to four equivalent In(2) and eight equivalent In(1) atoms to form MnIn12 cuboctahedra that share corners with four equivalent Mn(1)In12 cuboctahedra, corners with eight equivalent In(2)Mn4In8 cuboctahedra, edges with eight equivalent Mn(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Mn4In8 cuboctahedra, faces with four equivalent Mn(1)In12 cuboctahedra, faces with six equivalent In(2)Mn4In8 cuboctahedra, and faces with eight equivalent In(1)Mn4In8 cuboctahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent Mn(1), four equivalent In(1), and four equivalent In(2) atoms to form InMn4In8 cuboctahedra that share corners with twelve equivalent In(1)Mn4In8 cuboctahedra, edges with eight equivalent Mn(1)In12 cuboctahedra, edges with eight equivalent In(1)Mn4In8 cuboctahedra, edges with eight equivalent In(2)Mn4In8 cuboctahedra, faces with four equivalent Mn(1)In12 cuboctahedra, faces with four equivalent In(2)Mn4In8 cuboctahedra, and faces with ten equivalent In(1)Mn4In8 cuboctahedra. In the second In site, In(2) is bonded to four equivalent Mn(1) and eight equivalent In(1) atoms to form distorted InMn4In8 cuboctahedra that share corners with four equivalent In(2)Mn4In8 cuboctahedra, corners with eight equivalent Mn(1)In12 cuboctahedra, edges with eight equivalent In(2)Mn4In8 cuboctahedra, edges with sixteen equivalent In(1)Mn4In8 cuboctahedra, faces with four equivalent In(2)Mn4In8 cuboctahedra, faces with six equivalent Mn(1)In12 cuboctahedra, and faces with eight equivalent In(1)Mn4In8 cuboctahedra.
