title: Zn(II) coordination polymer of an in situ generated 4-pyridyl (4Py) attached bis(amido)phosphate ligand, [PO2(NH4Py)2]- showing preferential water uptake over aliphatic alcohols.
abstract: Two polymorphic 2D-coordination polymers of composition [ZnL(HCO2)]∞ were synthesized from an in situ generated ligand [PO2(NH(4)Py)2](-) (L(-)). The ligand L(-) was generated by a facile metal-assisted P-N bond hydrolysis reaction from the corresponding phosphonium salt 1, [P(NH(4)Py)4]Cl, or from the neutral phosphoric triamide 2, [PO(NH(4)Py)3]. The de-solvated sample of the polymer [ZnL(HCO2)]∞ features polar micropores and shows a type I isotherm for CO2 sorption whereas a type II behaviour was observed for N2. The vapour sorption isotherm of the de-solvated sample of [ZnL(HCO2)]∞ shows preferential adsorption of water vapour over aliphatic alcohols.
