Generation of a 4-crossing [2]-catenane motif by the 2D→2D parallel interpenetration of pairs of (4,4) sheets

Abstract

A fascinating new series of structures in which 4-crossing [2]-catenane motifs are formed between pairs of interpenetrating 2D sheets; moreover, the inclined orientation of the two interpenetrating nets with a layer leads to the wrapping of helical chains of one net around zigzag chains of the other.
