Synthesis and structural characterization of two novel cyano/isocyano bridged CuI coordination polymers: Catalytic activities in the synthesis of triazoles

In the present study, two novel polymeric copper(I) cyanide/isocyanide complexes with N,N′-bidentate Schiff base ligands ([Cu(LBr)CN]n and [Cu(LCl)CN]n) were successfully synthesized and characterized by employing FT-IR and elemental analysis. The single-crystal X-ray diffraction (SC-XRD) analysis was used to figure out the geometrical properties of the complexes, and the results showed that the copper ions are attached to N atoms of Schiff base ligands. The bond angles surrounding the Cu(I) ions revealed the distorted tetrahedral geometry of the complexes. Furthermore, the catalytic ability of these complexes was evaluated in the synthesis of triazoles under a conventional thermal environment.
