Abstract

The most impressive feature of the crystal structure of IrPr(6)Cl(11) 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 {IrPr(6)} clusters that are surrounded in a mixed {ZR(6)}X(i)(12)/{ZR(6)}X(i)(8) type by chlorido ligands with a rather complex connectivity, {IrPr(6)}(Cl(i-a-a)(4/3)Cl(a-i-a)(8/3)Cl(i-a)(6/2)Cl(a-i)(6/2))(e)(Cl(i-i)(2/2))(f), to a three-dimensional structure of tetragonally packed cluster-complex chains.
