Here, we report on the multicomponent self-assembly and single crystal X-ray diffraction study of a series of three interlocked mixed valence monoand hetero-metallic [2]-catenanes made of [2 2] metallo-grids. They show unique structural features and highlight the essential roles of both the Cu(II)/Cu(I) pair and of the conformationally adaptable organic ligands for achieving catenation of grids.
