Title: Materials Data on Ti2Se by Materials Project

Abstract

Ti2Se crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are six inequivalent Ti sites. In the first Ti site, Ti is bonded in a 4-coordinate geometry to four Se atoms. There are two shorter (2.60 Å) and two longer (2.65 Å) Ti–Se bond lengths. In the second Ti site, Ti is bonded in a 4-coordinate geometry to four Se atoms. There are a spread of Ti–Se bond distances ranging from 2.58–2.79 Å. In the third Ti site, Ti is bonded in a 3-coordinate geometry to three Se atoms. There are two shorter (2.55 Å) and one longer (2.61 Å) Ti–Se bond lengths. In the fourth Ti site, Ti is bonded in a distorted T-shaped geometry to three Se atoms. There are a spread of Ti–Se bond distances ranging from 2.62–2.74 Å. In the fifth Ti site, Ti is bonded to five Se atoms to form distorted edge-sharing TiSe5 trigonal bipyramids. There are a spread of Ti–Se bond distances ranging from 2.56–2.58 Å. In the sixth 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 2.58–2.88 Å. There are three inequivalent Se sites.more » In the first Se site, Se is bonded to seven Ti atoms to form distorted edge-sharing SeTi7 pentagonal bipyramids. In the second Se site, Se is bonded in a 8-coordinate geometry to eight Ti atoms. In the third Se site, Se is bonded in a 9-coordinate geometry to nine Ti atoms.« less
