a, Reaction scheme for catenane synthesis. b, Solid-state structure of the [3]catenane mcC40·(Ma)2. Thermal ellipsoids plotted at the 40% level. The macrocycles are coloured green, the phosphene ligands are blue and the oxygen atoms of the carbonyl ligands are red. c, nESI mass spectrum of the [5]rotaxane mcC80·(Ma)4 compared with the calculated isotopomer distribution for [M + 4H]4+.
