Reaction of a rigid triangular ligand 2,4,6-tris[4-(1H-imidazole-1-yl)phenyl]-1,3,5-triazine (TIPT) with Cd2+ ions afforded rare non-interpenetrating CdI2-type networks which display high thermostability and potential porosity; the topological character of the CdI2-type networks have been analyzed in comparison with three common uniform (4,4), (6,3) and (3,6) plane nets.

H3‐A(BF4)3 or H3‐D(BF4)3 with Ag2O yield trinuclear homoligand complexes [Ag3(L)2](BF4)3 (L=A, D). However, equimolar mixtures of H3‐A(BF4)3 and H3‐D(BF4)3 react with Ag2O under social self‐sorting to give the heteroligand assembly [Ag3(A)(D)](BF4)3. The same heteroligand assembly was obtained by transmetallation from mixtures of complexes [Ag3(A)2](BF4)3 and [Ag3(D)2](BF4)3. The transmetallation from

linking two hexakis-NHC ligands by three cyclobutane units to give complexes [Ag6 (2 a)](PF6 )6 and [Ag6 (2 b)](PF6 )6 bearing a dodecacarbene ligand. From the related nonakisimidazolium salt H9 -3(BF4 )9 , complex [Ag9 (4)](BF4 )9 bearing an octadecacarbene ligand was obtained. Removal of the templatemetals yielded very large, stable, polyimidazolium cations with 12 or 18 internal imidazolium groups.

catalytically active, cavity‐hosted, dispersed poly‐N‐heterocycliccarbene (NHC)‐anchored gold NPs. Owing to the stabilization of the NHC ligands and the effective confinement of the cage cavities, the as‐prepared poly‐NHC‐shell‐encapsulated AuNPs displayed promising stability towards heat, pH, and chemical regents. Most notably, all the Au@PCCs (PCC=polycarbene cage) exhibited excellent catalytic activities
