Hybrid Inorganic–Organic Polyrotaxane, Pseudorotaxane, and Sandwich

Inorganic copper­(I)/silver­(I) halide/pseudohalide components are used to thread classical organic tetracationic macrocycles, cyclobis­(paraquat-p-phenylene) and cyclobis­(paraquat-4,4′-biphenylene), to construct crystalline inorganic–organic adducts, featuring an unprecedented hybrid polyrotaxane and several unusual hybrid pseudorotaxanes and sandwiches.
