Abstract

Poorly soluble in the most part of organic solvents dimeric complexes \({\text{M}}{{{\text{g}}}_{{\text{2}}}}{\text{L}}_{2}^{2}\)·4DMF (I) and \({\text{N}}{{{\text{i}}}_{{\text{2}}}}{\text{L}}_{2}^{2}\)·4DMF (II) (L is 4,4'-(1,4-phenylenebis(azanylylidene))bis(3,6-di-tert-butyl-2-hydroxycyclohexa-2,5-dien-1-one dianion)) are synthesized by the reactions of magnesium and nickel acetates with the ditopic redox-active ligand of the hydroxy-para-iminoquinone type in a DMF solution. The molecular and crystal structures of the synthesized compounds are determined by X-ray diffraction analysis (CIF files CCDC nos. 2045665 (I) and 2045666 (II·3DMF)). The thermal stability is studied by thermogravimetry. The redox-active character of the organic bridging ligand in the dimeric complexes \({\text{M}}{{{\text{g}}}_{{\text{2}}}}{\text{L}}_{2}^{2}\)·4DMF and \({\text{N}}{{{\text{i}}}_{{\text{2}}}}{\text{L}}_{2}^{2}\)·4DMF is confirmed by the data of solid-phase electrochemistry.
