Abstract

As an extension of actinide-rotaxane complexes from uranium to transuranium, we report the first crystal structure of a neptunium-rotaxane complex, NRCP-1, in which an interwoven neptunium(v)-rotaxane coordination network incorporating a mechanically-interlocked [c2]daisy chain unit is promoted via the simultaneous coordination of cucurbituril (CB6) and axle molecules in [2]pseudorotaxane to Np^V.
