Imidazolines are a valuable class of organic compounds, namely ligands of imidazoline receptors, chiral ligands for metal catalysis, synthetic intermediates. The title compound has been prepared through a modified procedure, employing N-benzylethylenediamine and thiophene-2-carbaldehyde under the action of N-bromosuccinimide (NBS) in dichloromethane (DCM) in a good 78% yield.

In the polymeric title compound, [CuI(C10H8N4)]n, the CuIatom is in a four-coordinated tetrahedral geometry, formed by two I atoms and two pyridine N atoms from two different 4,4′-(diazenediyl)dipyridine (4,4′-azpy) ligands. Two μ2-I atoms link two CuIatoms to form a planar rhomboid [Cu2I2] cluster located on an inversion centre, where the distance between two CuIatoms is 2.7781 (15) Å and the Cu—I bond lengths are 2.6290 (13) and 2.7495 (15) Å. The bridging 4,4′-azpy ligands connect the [Cu2I2] clusters into a two-dimensional (2-D) double-layered grid-like network [parallel to the (10\overline{2}) plane], with a (4,4)-connected topology. Two 2-D grid-like networks interweave each other by long 4,4′-azpy bridging ligands to form a dense 2-D double-layered network. To the best of our knowledge, this interwoven 2-D→2-D network is observed for the first time in [Cu2I2]–organic compounds.

The synthesis and chemistry of heterocyclic N-oxide derivatives such as those from pyridine and indazole are very well-known due to their usefulness as versatile synthetic intermediates and their biological importance. These classes of organic compounds have been demonstrated in many interesting and amazing functionalities, particularly vital in the areas including metal complexes formation, catalysts design, asymmetric catalysis and synthesis, and medicinal applications (some potent N-oxide compounds with anticancer, antibacterial, anti-inflammatory activity, etc.). Therefore, the heterocyclic N-oxide motif has been successfully employed in a number of recent advanced chemistry and drug development investigations. In the present review, our primary aim was to provide a relevant summary focusing on the topics of organic synthesis and medical application potential of the compounds cited, which could be attractive and give some insights to researchers in the field. Therefore, we mainly highlight the importance of heterocyclic N-oxide derivatives including those synthesized from imidazole, indazole, indole, pyridazine, pyrazine, pyridine, and pyrimidine in organic syntheses and catalysis, and drug applications. Over the past years, a number of reviews have been published on the organic synthesis and catalysis of N-oxides. We thus concentrated on highlighting those rarely mentioned or recently reported systems.
