Fig. 23 Solid-state structures of some beautifully novel MIM architectures: (a) suit[2]ane [
33
],
(b) eightfold interlocked multicatenane [
154
], (c) hybrid organic-inorganic [4]rotaxane [
88
],
(d) [c2]daisy chain [
155
], where [c2] denotes that the molecule is cyclic and has two components,
(e) [5]catenane “molecular necklace” [
116
], (f) molecular Borromean Rings [
156
], (g) molecular
Solomon Link [
157
], and (h) interlocked coordination cages [
158
]. (a), (c), (e), and (g) reproduced

arises from doubly connecting the ring on both sides; and a “bonnane” [
152
] is the
product of connecting two or more rotaxane rings together. A joint effort from the
Vogtle and Sauvage groups [
144
] led to the beautifully symmetrical [4]catenane in
Fig.
22b
with a macrobicyclic core. Fig.

is a rotacatenane (rotaxane/catenane
combination) [
145
] from our own group. A cyclic [2]catenane dimer (Fig.
22d
)
from the Fujita group [
146
] and a cyclic [4]rotaxane (Fig.
22e
) from our group [
