Nb3Mo3AlSn crystallizes in the trigonal R3 space group. Nb(1) is bonded in a 2-coordinate geometry to two equivalent Mo(1), two equivalent Al(1), and two equivalent Sn(1) atoms. Mo(1) is bonded in a 2-coordinate geometry to two equivalent Nb(1), two equivalent Al(1), and two equivalent Sn(1) atoms. Al(1) is bonded to six equivalent Nb(1) and six equivalent Mo(1) atoms to form AlNb6Mo6 cuboctahedra that share edges with six equivalent Al(1)Nb6Mo6 cuboctahedra and faces with eight equivalent Sn(1)Nb6Mo6 cuboctahedra. Sn(1) is bonded to six equivalent Nb(1) and six equivalent Mo(1) atoms to form SnNb6Mo6 cuboctahedra that share edges with six equivalent Sn(1)Nb6Mo6 cuboctahedra and faces with eight equivalent Al(1)Nb6Mo6 cuboctahedra.
