Guaninium dihydrogenphosphite dihydrate

L. Bendheif, K. Bouchouit and N. Benali-Cherif

Abstract: The structure of the title compound, C₅H₆N₅O⁺·H₂PO₃^-·2H₂O, consists of a layer arrangement in which the organic cations are sandwiched between H₂PO₃^- inorganic sheets. In the crystal structure, the phosphite anions are linked together by short strong (P-O-HO-P) hydrogen bonds to form a two-dimensional network. Strong hydrogen bonds are responsible for the cohesion between organic-inorganic layers and maintain the stability of the structure.
