A new dinucleating N,O donor ligand (H2BPClNOL) and the structural and magnetic properties of two diiron complexes with the di-m-alkoxo motif

A new polidentade ligand, N-(2-hydroxybenzyl)-N-(2-pyridylmethyl) [(3-chloro)(2-hydroxy)]propylamine (H2BPClNOL), was synthesized and two Fe2III complexes containing the FeIII(m-alcoxo)2FeIII core were structurally and magnetically characterized. Complex [Fe2(BPClNOL)2(OAc)]ClO4 (1) differs from com...

Description
Summary:A new polidentade ligand, N-(2-hydroxybenzyl)-N-(2-pyridylmethyl) [(3-chloro)(2-hydroxy)]propylamine (H2BPClNOL), was synthesized and two Fe2III complexes containing the FeIII(m-alcoxo)2FeIII core were structurally and magnetically characterized. Complex [Fe2(BPClNOL)2(OAc)]ClO4 (1) differs from complex [Fe2(BPClNOL)2(H2O)2](ClO4)2.4H2O (2) by the presence of an acetate-bridge between the two iron centers. The complex with the acetate bridge is about 20 % less antiferromagnetically coupled than the complex without the acetate bridge.
