The inorganic–organic hybrid zinc phosphite poly[(μ₃-hydrogen phosphito-κ³O:O′:O′′)(piperidin-1-ium-4-car­box­yl­ate-κO)zinc(II)]

A new inorganic–organic hybrid zinc phosphite features an unusual (3,4)-connected two-dimensional inorganic zinc–phosphite layer with organic piperidin-1-ium-4-carboxyl­ate ligands appended to the sheets and protruding into the inter­layer region.
