Supramolecular complexes obtained from the interaction of violuric acid with manganese ion and nitrogenous ligands

This work describes the synthesis, spectroscopic characterization (Raman and infrared) and structural arrangement of three new supramolecular complexes named [Mn(H2Vi)2(H2O)4)](bpy)2 (1), [Mn(bpa)2(H2O)4](H2Vi)2 (2) and [Mn(bpp)2(H2Vi)2]·(bpp)2(H2O)2 (3); these compounds have been obtained making use of different building blocks such as 4,4′-bipyridyne (bpy), 1,2-bis(4-pyridyl)ethane (bpa) and 4,4′-trimethylene-dipyridine (bpp) acting as spacers...
