Bis(μ3-iodo)-pentakis(μ2-iodo)-penta-copper(I) – A fully ordered, isolated [Cu5I7]2− cluster

Two new compounds, [(C4H9)4P]2[Cu5I7] and [(C4H9)4P]2[Cu5I7]·CH3COCH2OH were synthesized by solvolysis and their crystal structures were solved. The first compound is disordered, but the solvate represents the first example of a fully ordered [Cu5I7]2− cluster. It displays a molecular symmetry very close to C2. Both compounds crystallize in space group P21/c.
