Abstract

Hf(TeCl2)3(Te)3 crystallizes in the orthorhombic Pbcm space group. The structure is one-dimensional and consists of twelve telloy molecules and two Hf(TeCl2)3 ribbons oriented in the (0, 0, 1) direction. In each Hf(TeCl2)3 ribbon, Hf4+ is bonded in an octahedral geometry to six Cl1- atoms. There are a spread of Hf–Cl bond distances ranging from 2.42–2.50 Å. There are two inequivalent Te+0.33+ sites. In the first Te+0.33+ site, Te+0.33+ is bonded in a water-like geometry to two equivalent Cl1- atoms. Both Te–Cl bond lengths are 3.15 Å. In the second Te+0.33+ site, Te+0.33+ is bonded in a single-bond geometry to one Cl1- atom. The Te–Cl bond length is 3.11 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Hf4+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Hf4+ atom. In the third Cl1- site, Cl1- is bonded in a distorted water-like geometry to one Hf4+ and one Te+0.33+ atom. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Hf4+ and one Te+0.33+ atom.
