Coordination Architectures of 5-Aminotetrazole-1-Acetic Acid (Hatza) Flexible Ligand and 2,2′-Bipy Rigid Auxiliary Ligand with Mn(II)

Abstract

Two Mn(II) coordination polymers [Mn(atza) 2 (H 2 O) 2 ] n (1) and [Mn(atza)(2,2 0 -bipy)(H 2 O)] n ÁnClO 4 (2) (2) [atza = 5-aminotetrazole-1-acetato] have been synthesized and characterized by X-ray diffraction analysis, element analysis and IR spectra. Each Mn(II) ion has a distorted octahedral coordination geometry in 1 and 2, and the Mn(II) ion centres are connected through the atza bridging ligands to form a 1D ribbon-type polymeric chain for 1 and a 2D layer structure for 2.
