A New Organically Templated Zinc Phosphite Synthesized in Phosphorous Acid Flux and Its Hydrothermal Analogue

A new organically templated zinc phosphite, (H₂bbp)₂·Zn₆(HPO₃)₈ (1) (bbp = 1,3-bis(4-pyridyl)propane), has been synthesized in a water-free flux of H₃PO₃. This compound possesses a new layered structure different from the analogue obtained in the corresponding hydrothermal synthesis, Zn(bbp)_0.5(HPO₃)·0.5H₂O (2).
