Abstract

Bi3TeCl10Te crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two tellurium molecules and one Bi3TeCl10 sheet oriented in the (0, 0, 1) direction. In the Bi3TeCl10 sheet, there are three inequivalent Bi+2.67+ sites. In the first Bi+2.67+ site, Bi+2.67+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Bi–Cl bond distances ranging from 2.53–3.10 Å. In the second Bi+2.67+ site, Bi+2.67+ is bonded in a 4-coordinate geometry to four Cl1- atoms. There are a spread of Bi–Cl bond distances ranging from 2.49–3.25 Å. In the third Bi+2.67+ site, Bi+2.67+ is bonded in a 6-coordinate geometry to six Cl1- atoms. There are a spread of Bi–Cl bond distances ranging from 2.56–3.11 Å. Te1+ is bonded in a single-bond geometry to one Cl1- atom. The Te–Cl bond length is 3.14 Å. There are ten inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a water-like geometry to two Bi+2.67+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent Bi+2.67+ atoms. In the third Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two Bi+2.67+ atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to two Bi+2.67+ atoms. In the fifth Cl1- site, Cl1- is bonded in a distorted trigonal non-coplanar geometry to three Bi+2.67+ atoms. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one Bi+2.67+ atom. In the seventh Cl1- site, Cl1- is bonded in a single-bond geometry to one Bi+2.67+ atom. In the eighth Cl1- site, Cl1- is bonded in a single-bond geometry to one Bi+2.67+ atom. In the ninth Cl1- site, Cl1- is bonded in a single-bond geometry to one Bi+2.67+ atom. In the tenth Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to one Bi+2.67+ and one Te1+ atom.
