Ti2Sn crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to six equivalent Ti(2) and five equivalent Sn(1) atoms to form a mixture of corner and face-sharing TiTi6Sn5 trigonal bipyramids. In the second Ti site, Ti(2) is bonded in a 14-coordinate geometry to two equivalent Ti(2), six equivalent Ti(1), and six equivalent Sn(1) atoms. Sn(1) is bonded in a 11-coordinate geometry to five equivalent Ti(1) and six equivalent Ti(2) atoms.

In the first Ti site, Ti(1) is bonded to six equivalent Ti(2) and five equivalent Sn(1) atoms to form a mixture of corner and face-sharing TiTi6Sn5 trigonal bipyramids. All Ti(1)-Ti(2) bond lengths are 3.07 Å. There are three shorter (2.73 Å) and two longer (2.81 Å) Ti(1)-Sn(1) bond lengths. In the second Ti site, Ti(2) is bonded in a 14-coordinate geometry to two equivalent Ti(2), six equivalent Ti(1), and six equivalent Sn(1) atoms. Both Ti(2)-Ti(2) bond lengths are 2.81 Å. All Ti(2)-Sn(1) bond lengths are 3.07 Å. Sn(1) is bonded in a 11-coordinate geometry to five equivalent Ti(1) and six equivalent Ti(2) atoms.
