Materials Data on Ti3Nb3Sn2 by Materials Project
Ti3Nb3Sn2 crystallizes in the trigonal R32 space group. The structure is three-dimensional. Ti is bonded in a 6-coordinate geometry to two equivalent Nb and four equivalent Sn atoms. Both Ti–Nb bond lengths are 2.65 Å. There are two shorter (2.94 Å) and two longer (2.97 Å) Ti–Sn bond lengths. Nb is bonded in a 6-coordinate geometry to two equivalent Ti and four equivalent Sn atoms. There are two shorter (2.96 Å) and two longer (2.97 Å) Nb–Sn bond lengths. Sn is bonded to six equivalent Ti and six equivalent Nb atoms to form a mixture of edge and face-sharing SnTi6Nb6 cuboctahedra.
