Structural variety and dehydration in 3-aminopyridine–hypodiphosphoric acid–water system

Abstract

Organic–inorganic salts and ionic co-crystals of hypodiphosphoric acid (H4P2O6) with 3-aminopyridine (3ap) have been synthesized and characterized by X-ray diffraction (single-crystal and micro-powder), thermogravimetry and Fourier-transform infrared spectroscopy. (3apH)2(H2P2O6)∙0.5H4P2O6∙H2O (1),...
