Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p> Solvothermal reactions of 1‐cyanobenzoimidazole, NaN₃, and hydrated <italic>M</italic>^IICl₂ (<italic>M</italic> = Mn, Zn, Cu) in a mixture of EtOH/H₂O in the presence of NH₄Cl afforded a mononuclear complex [Mn(L¹)₂(H₂O)₄] (<bold>1</bold>), a 3D polymer [Zn(L¹)(OH)]<italic>_n</italic> (<bold>2</bold>), and a linear polymer {[Cu(Bim)]}<italic>_n</italic> (<bold>3</bold>), respectively, where the ligand L¹ is formed in‐situ from [3+2] dipolar cycloaddition of N₃^– with nitrile and the ligand Bim is in‐situ formed from C–N bond cleavage of 1‐cyanobenzoimidazole. (L¹ = 5‐benzoimidazoyltetrazolate, Bim = benzoimidazole). All the compounds were characterized by IR spectroscopy, elemental analysis, and thermo‐gravimetric analysis (TGA), and their structures were determined by X‐ray crystallography. The solid state luminescent properties of <bold>2</bold> and <bold>3</bold> were also investigated at room temperature.</p> </abstract>
