A bis-polydentate oxamate-based achiral ligand able to stabilize a macrocyclic mixed valence compound or induce a 1D helical chain
Abstract
The reaction of the N-(2-hydroxyphenyl)oxamate ligand (ohpma) has been investigated with cobalt(II) and copper(II) ions. It has led to two coordination compounds, (TMA) 3 [{Co III (ohpma) 2 Co II (MeOH) 2 } 3 ]·10H 2 O·5MeOH (1) and (HNEt 3)[Cu(ohpma)] (2). Both compounds have been characterized by single-crystal X-ray diffraction and magnetometry. The X-ray diffraction studies have revealed atypical structures that are not commonly observed in oxamate coordination chemistry with a macrocyclic arrangement for the mixed-valence cobalt-based complex 1, and a helical chiral chain for compound 2. In the latter, the bis-polydentate nature of the (ohpma) 3-ligand with distinct tridentate and bidentate coordination sites creates a chirogenic center on the copper ion. The investigation of the magnetic properties shows a field-induced single-molecule magnet behavior for complex 1, while antiferromagnetic interactions dominate the behavior of 2.
