Synthesis and Crystal Structures of One-Dimensional Chain Copper(II) Complexes of Two Phenol-Containing Schiff-Base Ligands

Abstract

Two copper(II) complexes of the tridentate Schiff-base ligands (L 1 )and (L 2 ) -, [CuL 1 (µ-Br)]∞ (1) and [CuL 2 (µ1,3-N3)]∞ (2), have been synthesized and characterized. The ligands [(L 1 )and (L 2 )are the deprotonated forms of 2-[(2-morpholin-4-ylethylimino)methyl]phenol (HL 1 ) and 2-[(2-piperidin-1-ylethylimino)methyl]phenol (HL 2 ), respectively]. X-Ray structure determinations carried out on complexes 1 and 2 reveal that both complexes are mono(µ-bromo)-bridged (for 1) or mono(µ1,3-azido)-bridged (for 2) square pyramidal copper(II) one-dimensional chain polymeric complexes.
