Abstract Reaction of a methanolic copper(II) acetate solution with tetrazolyl enol derivatives 2a (HL2) or 2b (HL3) leads to the formation of the corresponding 2D-coordination polymers 4 (∞2 [CuL22]) and 5 (∞2 [CuL23]), respectively. Single-crystal X-ray diffraction of the supramolecular species 4 and 5 established unequivocally the structures of the regioisomeric coordination polymers. On the contrary, reactions of 2c (HL4) with methanolic copper(II) acetate solution and 2b (HL3) with methanolic zinc(II) acetate solution yield mononuclear chelate complexes 11 ([CuL42]) and 12 ([ZnL23(MeOH)2]). The structures of 11 and 12 have been established by X-ray structure analysis.
