Materials Data on Ti(NCl)3 by Materials Project
Ti(NCl)3 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one Ti(NCl)3 ribbon oriented in the (1, 0, 0) direction. Ti4+ is bonded to two equivalent N+0.33- and four Cl1- atoms to form distorted edge-sharing TiN2Cl4 octahedra. There are one shorter (2.09 Å) and one longer (2.18 Å) Ti–N bond lengths. There are a spread of Ti–Cl bond distances ranging from 2.20–2.70 Å. There are three inequivalent N+0.33- sites. In the first N+0.33- site, N+0.33- is bonded in a distorted trigonal planar geometry to two equivalent Ti4+ and one N+0.33- atom. The N–N bond length is 1.23 Å. In the second N+0.33- site, N+0.33- is bonded in a linear geometry to two N+0.33- atoms. The N–N bond length is 1.14 Å. In the third N+0.33- site, N+0.33- is bonded in a single-bond geometry to one N+0.33- atom. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Ti4+ atom. In the second Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent Ti4+ atoms. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Ti4+ atom.
