1-Methylbenzimidazole (cas: 1632-83-3) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Computed Properties of C8H8N2

Heptadentate, Octadentate, Or Even Nonadentate? Denticity in the Unexpected Formation of an All-Carbon Donor-Atom Ligand in RhIII(Cp*)(Anthracenyl-NHC) Complexes was written by Lee, Betty Y. T.;Phillips, Andrew D.;Hanif, Muhammad;Tong, Kelvin K. H.;Sohnel, Tilo;Hartinger, Christian G.. And the article was included in Inorganic Chemistry in 2021.Computed Properties of C8H8N2 This article mentions the following:

Investigations on incorporating an N-flanking anthracenyl moiety to [Rh(Cp*)(NHC)Cl2] complexes surprisingly led to the formation of an intramol. C-C bond between the Cp* and anthracenyl moieties, with addnl. auxiliary interactions between the metal and the anthracenyl ring system. In silico modeling supports a reaction mechanism whereby Rh(η4-tetramethylfulvene) intermediates undergo metallocycloaddn. and the abstraction of a chlorido ligand, affording unique cationic complexes that feature Rh centers coordinated by a nonadentate ligand with exclusively carbon donor atoms. Some Rh-C interactions were extremely weak but nevertheless exhibited covalent bonding character. These weak Rh-C interactions were readily displaced by stronger electron donors, and the nonadentate ligand reverted to the heptadentate coordination mode observed in the intermediate. As far as we are aware, this study provides the first conclusive evidence of complexes bearing a single nonadentate κ9-coordinating ligand that features only carbon donors bound to a metal center. In the experiment, the researchers used many compounds, for example, 1-Methylbenzimidazole (cas: 1632-83-3Computed Properties of C8H8N2).
