Abstract

Ti45Se16 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are twenty-three inequivalent Ti sites. In the first Ti site, Ti is bonded in a linear geometry to two equivalent Se atoms. Both Ti–Se bond lengths are 2.61 Å. In the second Ti site, Ti is bonded in a 4-coordinate geometry to four Se atoms. There are two shorter (2.62 Å) and two longer (2.65 Å) Ti–Se bond lengths. In the third Ti site, Ti is bonded in a distorted L-shaped geometry to two equivalent Se atoms. Both Ti–Se bond lengths are 2.57 Å.

In the eighteenth Ti site, Ti is bonded in a distorted L-shaped geometry to two equivalent Ti and two Se atoms. Both Ti–Ti bond lengths are 2.81 Å. There are one shorter (2.71 Å) and one longer (2.76 Å) Ti–Se bond lengths. In the nineteenth Ti site, Ti is bonded in a distorted L-shaped geometry to two equivalent Ti and two Se atoms. Both Ti–Ti bond lengths are 2.70 Å. There are one shorter (2.60 Å) and one longer (2.72 Å) Ti–Se bond lengths. In the twentieth Ti site, Ti is bonded in a 12-coordinate geometry to nine Ti atoms. There are a spread of Ti–Ti bond distances ranging from 2.75–3.02 Å. In the twenty-first Ti site, Ti is bonded in a 4-coordinate geometry to four Se atoms. There are two shorter (2.61 Å) and two longer (2.62 Å) Ti–Se bond lengths. In the twenty-second Ti site, Ti is bonded in a distorted L-shaped geometry to three equivalent Ti and two equivalent Se atoms. Both Ti–Se bond lengths are 2.58 Å. In the twenty-third Ti site, Ti is bonded in a 5-coordinate geometry to five Se atoms. There are a spread of Ti–Se bond distances ranging from 2.59–2.88 Å. There are eight inequivalent Se sites. In the first Se site, Se is bonded in a 9-coordinate geometry to nine Ti atoms. In the second Se site, Se is bonded to seven Ti atoms to form distorted edge-sharing SeTi7 pentagonal bipyramids.
