description: (CdCl3)2Cd2Te6O13 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one CdCl3 ribbon oriented in the (1, 0, 0) direction and one Cd2Te6O13 sheet oriented in the (0, 0, 1) direction. In the CdCl3 ribbon, there are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to six Cl1- atoms to form edge-sharing CdCl6 octahedra. There are a spread of Cd–Cl bond distances ranging from 2.60–2.80 Å. In the second Cd2+ site, Cd2+ is bonded to six Cl1- atoms to form edge-sharing CdCl6 octahedra. There are a spread of Cd–Cl bond distances ranging from 2.58–2.81 Å. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Cd2+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Cd2+ atom. In the third Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Cd2+ atom. In the fourth Cl1- site, Cl1- is bonded in a water-like geometry to two Cd2+ atoms. In the fifth Cl1- site, Cl1- is bonded in a distorted water-like geometry to two Cd2+ atoms. In the sixth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three Cd2+ atoms. In the Cd2Te6O13 sheet, there are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cd–O bond distances ranging from 2.36–2.83 Å. In the second Cd2+ site, Cd2+ is bonded in a 8-coordinate geometry to seven O2- atoms. There are a spread of Cd–O bond distances ranging from 2.33–2.84 Å. There are six inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–1.97 Å. In the second Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.23 Å. In the third Te4+ site, Te4+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.73 Å. In the fourth Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–2.19 Å. In the fifth Te4+ site, Te4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distances ranging from 1.97–2.33 Å. In the sixth Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.20 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Cd2+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Cd2+ and two Te4+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Cd2+ and one Te4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Cd2+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Cd2+ and two Te4+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Cd2+ and one Te4+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Te4+ atoms. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three Te4+ atoms. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and three Te4+ atoms. In the tenth O2- site, O2- is bonded in a 4-coordinate geometry to three Cd2+ and one Te4+ atom.
