pH‐Directed Synthesis of Two Luminescent Zinc(II) Coordination Compounds based on 5‐Aminotetrazole‐1‐propanoic Acid

Abstract

Two Zn II -tetrazole-carboxylate coordination compounds are reported, mononuclear [Zn(atzpa) 2 (H 2 O) 4 ]·2H 2 O (1) and onedimensional [Zn(atzpa) 2 (H 2 O) 2 ] n (2), derived from 5-aminotetrazole-1-propanoic acid (Hatzpa). The structures of both compounds are determined by the pH value of the reaction system. The luminescence properties of Hatzpa and the compounds were investigated at room
