strategy for the synthesis of a “cationic-cage” (CC-Ag) has been developed via metal–carbene (M–CNHC) bond formation followed by imine bond condensation. Reaction of a trigonal trisimidazolium salt H3L(PF6)3 functionalized with three flexible N-phenyl-aldehyde pendants with silver oxide yielded a trinuclear tricationic organometallic cage (OC-Ag). Subsequent treatment of the organometallic cage (OC-Ag) with

A procedure for the synthesis of three‐dimensional hexakisimidazolium cage compounds has been developed. The reaction of the trigonal trisimidazolium salts H3L(PF6)3, decorated with three N‐olefinic pendants, and silver oxide yielded trinuclear trisilver(I) hexacarbene molecular cylinders of the type [Ag3L2]3+ with the olefinic pendants from the two different tricarbene ligands arranged in three pairs

the formation of a water‐soluble semi‐cylindrical cage with a hydrophobiccavity, which was separately crystallized with hydrophilic‐ and hydrophobic guests. The parent cage was found to catalyze the Knoevenagel condensation reaction of a series of aromatic mono‐aldehydes with active methylene compounds, such as Meldrum′sacid or 1,3‐dimethylbarbituric acid. The confined hydrophobic nanospace within

to form ortho‐carborane complex 1d. A self‐assembled triangular prism cage 2a consisting of binuclear half‐sandwich metal precursors [Cp*2Rh2(μ‐BiBzIm)]Cl2 (BiBzIm = 2,2′‐bisbenzimidazole) ligands and L2 were found to capsulated a triphenylene in cage. Another two kinds of prismatic cages (3a and 3b) were obtained from the reactions of the bis‐chelating‐coordinated [Cp*2Rh2(μ‐CA)]Cl2(CA = chloranilate)
