“…Consequently books [14–16] and reviews cover the range from NHC structures in the light of their early history [17], syntheses [6,18], coordination chemistry [19–20], and catalysis [21–22], to biological activities of NHC complexes [23–24]. In the last decade, attention has also been directed to anionic N-heterocyclic carbenes [25].…”

The mesomeric betaine imidazolium-1-ylphenolate forms a borane adduct with tris(pentafluorophenyl)borane by coordination with the phenolate oxygen, whereas its NHC tautomer 1-(2-phenol)imidazol-2-ylidene reacts with (triphenylphosphine)gold(I) chloride to give the cationic NHC complex [Au(NHC)2][Cl] by coordination with the carbene carbon atom. The anionic N-heterocyclic carbene 1-(2-phenolate)imidazol-2-ylidene gives the complexes [K][Au(NHC−)2], [Rh(NHC−)3] and [Ni(NHC−)2], respectively. Results of four single crystal analyses are presented.

“…Flexible MOFs are interesting 22 and while NHCs have been incorporated into MOFs, 23 simply attaching NHCs to the copper paddlewheel centres has, to our knowledge, not yet been reported. Given the predicted effects on the structures and the fact that the Cu(II)-NHC-carboxylate complex is a hydrosilylation precatalyst, 17 the properties of partially-or fully-capped NHC CPW MOFs, if they can be synthesised, are certain to be different and may potentially be very interesting compared to current systems.…”

“…Zeolite imidazolate frameworks (ZIFs), a sub‐class of metal organic frameworks (MOFs), are porous hybrid materials that recently have received appreciable attention . Their structure is based upon four tetrahedral units, wherein metal ions such as Zn 2+ are connected to the imidazolate ligands and form units analogous to the [SiO 2 ] tetrahedra in zeolites .…”

We demonstrate the synthesis of isostructural zeolitic imidazole framework (ZIF‐8) using four distinct synthetic methods. Subsequently, the variations in physicochemical properties were analyzed through the catalytic reaction of CO2 cycloaddition of epoxide. It was thus demonstrated that simply by changing the type of synthetic method for the preparation of ZIF‐8, the physicochemical properties were changed significantly which in turn influenced the catalytic activity of ZIF‐8. It was found that the synthetic method affected the crystal growth and consequently influenced the physicochemical properties which are crucial aspects in metal–organic framework applications. There is an almost exponential relationship between the reactivity of various ZIF‐8 samples in CO2 cycloaddition of epoxide and the surface area, CO2 adsorption and pore volume.
