description: CuGa6Sb7(TeCl3)8 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cu1+ is bonded in a linear geometry to two equivalent Cl1- atoms. Both Cu–Cl bond lengths are 2.16 Å. There are three inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Ga–Cl bond distances ranging from 2.17–2.29 Å. In the second Ga3+ site, Ga3+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Ga–Cl bond distances ranging from 2.19–2.22 Å. In the third Ga3+ site, Ga3+ is bonded in a tetrahedral geometry to four Cl1- atoms. There are a spread of Ga–Cl bond distances ranging from 2.20–2.23 Å. There are four inequivalent Sb3+ sites. In the first Sb3+ site, Sb3+ is bonded in an octahedral geometry to six Te2- atoms. There are a spread of Sb–Te bond distances ranging from 3.05–3.07 Å. In the second Sb3+ site, Sb3+ is bonded in a rectangular see-saw-like geometry to three Te2- and one Cl1- atom.
