A novel N-donor bridging receptor R: 4,40-methanediylbis(2-ethyl-5-methyl-1H-imidazole) has been synthesized from 2-ethyl-4-methyl-1H-imidazole and formaldehyde in the presence of potassium hydroxide. This receptor then formed complexes with different transition metals ([Co(NO3)2, CoCl2, Ni(NO3)2 and CuCl2]) in different solvent systems and obtained ?ve different complexes. Wherein, the complex formation of R with Co(NO3)2 resulted in two different structures in methanol and acetonitrile, respectively. A thorough structural investigation of the present receptor and the resulted ?ve complexes show that the NH group of the receptor, the organic anions and solvent molecules play a key role in the construction of the ?ve intriguing architectures. We also prepared molecular Hirshfeld surface and ?ngerprint plot for R as well as the ?ve complexes, which revealed the in?uences of different metals to the coordinate behavior of R in terms of intermolecular interactions.
