Abstract
A new pillard
crystal packing of a hydrated [Zn(PABA)2(H2O)]H2O
(PABA = p-aminobenzoate) 1 was obtained
starting from a Layered Zinc Hydroxide with PABA as intercalated organic substrate.
Compound 1 was characterized in the solid state by crystal
structure analysis and in solution by 13C- and 1H-NMR
spectroscopy. In contrast to the known hydrate of Zn(PABA)2 the water molecules of crystal packing of 1 are involved in
the coordination sphere of the metal centers, forming hydrogen bonding interactions
between amino groups of PABA and water molecules.
