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
## Abstract Diastereomeric mixtures of tricyclic 3‐styrylpyrazolines have been prepared by the reaction of 3‐cynnamylidenechroman‐4‐ones and their 1‐thio analogs with hydrazine in hot acetic acid or propionic acid solutions. The diastereomeric mixtures were separated by column chromatography to obt
## Abstract ^1^H and ^13^C NMR assignments of bipyridine helicate complexes and their precursor ligands were achieved using gradient‐based homo‐ and hetero‐correlated 2D experiments. The observed trends in ^1^H and ^13^C chemical shift variations [Δδ(H) and Δδ(C)], on passing from the ligands to th
