The structure described by Ti3Nb3Sn2 crystallizes in the trigonal R32 space group. Ti(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1) and four equivalent Sn(1) atoms. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Ti(1) and four equivalent Sn(1) atoms. Sn(1) is bonded to six equivalent Ti(1) and six equivalent Nb(1) atoms to form a mixture of edge and face-sharing SnTi6Nb6 cuboctahedra. is represented by the CIF card [CIF]
