Heterometallic Tetrazole Coordination Polymer Formed through 2 + 3 Cycloaddition Reaction between Inorganic Complexes in the Presence of Lewis Acid

The two in situ 2 + 3 intermolecular cycloaddition reactions between inorganic complexes bis(3-cyanopyrdine)copper(II)azide (A) offer homometallic and heterometallic 3D novel tetrazole coordination polymers, (3-C5H4N-CN4)2Cu(I)2 (1) and (3-C5H4N-CN4)Cu(I)Cd(II)Cl2 (2), respectively, in the presence of Lewis acid CuCl2 and CdCl2 in which A is used to replace the organic cyano group and NaN3 during Sharplessʼs tetrazole synthesis. Their interesting luminescent properties are reported.
