Endohedral Metal Complexes of Cyclophanes

Complexes of π-Prismands with Gallium(I)

“…Examples in which the outside of the π system (e.g. B ) is attached to the metals are legion, whereas so-called endohedral cyclophanes ( C ) are rare (Scheme ). One of the first examples of the C type was the complex between Ag(I) triflate and [2.2.2]paracyclophane ( 1 ), which was followed by a series of Ag(I) triflate complexes with [2.2.2]-and [2.2.1]cyclophanes of variable connectivities. , In most cases the silver is bound to one double bond or to one carbon atom, respectively, of each of the three phenyl rings.…”

The coordination sphere is supplemented by one oxygen atom of the triflate anion. − …”

Structural Analyses of tetrathiadodecahydro[3.3.3.3]paracyclophane Complexes with Copper(I) and Silver(I)

“…The formation of the dimer is attributed to the larger ring strain in the trans 10 of Cu (I) and Ag(I) does not impose a preferred coordination [20][21] 2 studied to some extent. 22 Amongst these studies, the most bridge, and the silver ion tends to be a guest present in the bonding fashion is different from those in the literature.
