Fig. 14 Examples of beautiful X-ray crystal structures of MIMs. (a) The first crystal structure of a
MIM - Sauvage's [2]catenane [
83
]. (b) A branched heptacatenane [
84
] has a dizzying number of
interlocked macrocycles for a discrete molecule, appealing Euclidean shape, and intriguing
intermolecular interactions (p-p, C-H-p, H-bonding). (c) Two identical catenanes in a supramo-
lecular complex - a self-complexing [2]catenane [
85
]. (d) Two translational isomers of a bistable
[2]catenane, which were simultaneously crystallized from the same solution and isolated by hand-
picking from the mother liquor [
86
]. (e) Dynamically assembled [4]rotaxane, forced into a rigid-
rod shape by
-stacking interactions [
87
]. (f) The first inorganic-organic hybrid [2]rotaxane,
simple and elegant [
88
]. Reproduced with permission from [

spanning a prodigiously productive and iconoclastic academic career. This latter-
day wizard of chemical crystallography unraveled the solid-state structures
of hundreds of MIMs during two decades following the first report [

donor-acceptor [2]catenane in 1989. In addition to the sheer abundance of his
