Mono-anionic succinic acid bridged cationic cobalt(III/II/III) compounds of N2O2 donor ‘reduced Schiff base’ ligands containing perchlorate counter ions: Synthesis, structures and different non-covalent interactions in self-assembly

Abstract

Synthesis and characterization of two centrosymmetric cobalt(III/II/III) compounds, [CoII{(μ-L1)(μ-OOCCH2CH2COOH)CoIII(DMF)}2](ClO4)2 (1) and [CoII{(μ-L2)(μ-OOCCH2CH2COOH)CoIII(DMF)}2](ClO4)2·2CH3CHO (2) with two tetradentate ligands, H2L1 (2,2-dimethyl-1,3-propanediyl)bis(iminomethylene)bis(phenol) and H2L2 (2,2-dimethyl-1,3-propanediyl)bis(iminomethylene)bis(4-chlorophenol), and succinate as anionic co-ligands have been reported. Single crystal X-ray diffraction studies have confirmed the structures of the compounds.
