Supramolecular interactions through lone pair(lp)-π and hydrogen bonding in cobalt(III) and manganese(II) derivatives of N,N′-dimethylvioluric acid: A combined experimental and theoretical study

Synthesis, X-ray crystal structure determination, TGA, cyclic voltammetry and DFT calculations of two Co(III) and Mn(II) complexes containing N,N′-dimethylviolurate as ligand or counteranion were carried out. Interesting supramolecular assemblies in the solid state structures, especially lone pair(lp)-π interactions in compound 1 and hydrogen bonding network in compound 2, were observed.
