Two examples of mixed alkenyl/aryl organocopper­(I) aggregates possessing conjugated alkenyl/aryl C–Cu bonds were synthesized by transmetalation of zirconaindenes with CuCl. Single-crystal X-ray structural analysis revealed tetrameric and hexameric structures. Butadienyl copper­(I) aggregates were also synthesized and structurally characterized for further comparison. The preliminary reaction chemistry of the copper­(I) aggregates was studied.
