Formation of an interlocked double-chain from an organic–inorganic [2]rotaxane

Abstract

Here we show that a structure containing a polymeric interlocking daisy chain is obtained from the reaction of an inorganic–organic [2]rotaxane [HB{Cr^III₇Ni^II(μ-F)₈(O₂C^tBu)₁₆}], where B is an organic thread terminated with a bi-pyridyl unit, with an oxo-centered metal carboxylate triangle [Fe^III₂Co^II(μ₃-O)(O₂C^tBu)₆(HO₂C^tBu)₃].
