The title compound, poly[dizinc(II)‐μ‐ethylenediamine‐di‐μ‐(hydrogen phosphito)], β‐[H 2 N(CH 2 ) 2 NH 2 ] 0.5 [ZnHPO 3 ] or [Zn 2 (HPO 3 ) 2 (C 2 H 8 N 2 )] n , is a hybrid organic/inorganic solid built up from ethylenediamine molecules (which lie about inversion centres), Zn 2+ cations (coordinated by three O atoms and one N atom) and HPO 3 2− hydrogen phosphite groups. The organic species bond to the Zn atom as unprotonated ligands, acting as bridges between infinite ZnHPO 3 layers that propagate as very buckled (001) sheets. The zincophosphite sheets contain polyhedral four‐ and eight‐membered rings in a 4.8 2 topology. β‐[H 2 N(CH 2 ) 2 NH 2 ] 0.5 ·ZnHPO 3 complements the previously described α modification of the same stoichiometry [Rodgers & Harrison (2000). Chem. Commun . pp. 2385–2386].
