Formation of H-bonding networks in the solid state structure of a trinuclear cobalt(iii/ii/iii) complex with N 2 O 2 donor Schiff base ligand and glutaric acid as bridging co-ligand: synthesis, structure and DFT study.

A trinuclear linear mixed-valence centrosymmetric cobalt(iii)-cobalt(ii)-cobalt(iii) complex, [Co ^II {(μ-L)(μ-Hglu)Co ^III (OH ₂ )} ₂ ](ClO ₄ ) ₂ ·6H ₂ O has been synthesized during tetradentate N ₂ O ₂ donor 'Schiff base' ligand, H ₂ L { N , N '-bis(salicylidene)-1,3-diaminopropane} and glutaric acid (H ₂ glu) as anionic co-ligand. The complex has been characterized by spectroscopic measurements and its solid state structure has been determined by single crystal X-ray diffraction analysis. The supra-molecular assembly formed by the hydrogen bonding interactions in the solid state of the complex has been analysed using DFT calculations.
