Materials Data on Ti6Sn5 by Materials Project

Ti6Sn5 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Ti sites. In the first Ti site, Ti is bonded in a 7-coordinate geometry to four equivalent Ti and seven Sn atoms. All Ti–Ti bond lengths are 3.12 Å. There are a spread of Ti–Sn bond distances ranging from 2.85–2.99 Å. In the second Ti site, Ti is bonded in a 12-coordinate geometry to six Ti and six Sn atoms. Both Ti–Ti bond lengths are 2.86 Å. There are four shorter (2.83 Å) and two longer (3.04 Å) Ti–Sn bond lengths. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to eight Ti atoms. In the second Sn site, Sn is bonded in a 9-coordinate geometry to nine Ti atoms. In the third Sn site, Sn is bonded in a 6-coordinate geometry to six equivalent Ti and two equivalent Sn atoms. Both Sn–Sn bond lengths are 2.86 Å.
