X-ray diffraction and IR spectroscopic studies on the proton sponge 2,7-dichloro-1,8-bis(dimethylamino)naphthalene and its adduct with HBr were performed. It was shown that the presence of the chlorine atoms in positions 2 and 7 leads to some change of conformation with respect to the free molecule.

An ionic complex of 1,8-bis(dimethylamino)naphthalene with picrolonic acid was studied by C and 1 H magic angle spinning and x-ray diffraction. Structural and spectroscopic features of this compound were investigated. The detailed x-ray structure of this complex is described. A multicentre model of
