Chains of Face-Sharing {ZPr(6)} Octahedra with Alternating Endohedral Iridium Atoms and Chloride Ions in {(Ir,Cl)Pr-6}Cl-10
The most impressive feature of the crystal structure of IrPr6Cl11 is chains of face-sharing {Pr-6} octahedra that encapsulate, alternatingly, iridium atoms and chloride ions, according to the formulation {(Ir,Cl)Pr-6}Cl-10. An alternative description of the structure is the connection of isolated {IrPr6} clusters that are surrounded in a mixed {ZR(6)}X-12(i)/{ZR(6)}X-8(i) type by chlorido ligands with a rather complex connectivity, {IrPr6}(Cl(4/3)(i-a-a)Cl(8/3)(a-i-a)Cl(6/2)(i-a)Cl(a-)i(6/2))(e), (Cli-i2/2)(f), to a three-dimensional structure of tetragonally packed cluster-complex chains.
