The electronic structure, stability, acidity, topological properties and charge transfer of octahedral magnesium-carboxylate complexes have been investigated at M05-2X/6-311G** level of theory. The interaction energy studies confirm the stability of the pentahydrated magnesium compounds. The calculated pK values using SMD solvation model through the deprotonation of metal-ion bound water molecule vary from 15.08 to 19.36, enunciate the role of Mg-O bonds on the acidity of the Mg complexes. The closed shell ionic interactions of Mg-ligand bonds are assessed by the atoms in molecules (AIM) and the electron localization function (ELF) analyses. A reduced density gradient approach is utilized to explore the weak interactions including dihydrogen bonds.

A series of magnesium carboxylate complexes containing intramolecular NH···O hydrogen bonds were synthesized. Their molecular structures were determined by X-ray analysis. A direct NH···O hydrogen bond to the coordinated oxygen atom elongated the Mg-O bond, while a hydrogen bond to the carbonyl group shortened the Mg-O bond.
