The novel salt of a geminal diol 4-(dihydroxymethyl)pyridinium hydrogensquarate was derived from isonicotinaldehyde and squaric acid in water. Two polymorphs were characterized by means of single crystal X-ray diffraction and linear-polarized infrared (IR-LD) spectroscopy of oriented colloids in nem
