An Infinite Water Chain Passes through an Array of Zn(II) Metallocycles Built with a Podand Bearing Terminal Carboxylates

A podand bearing three carboxylic acid groups was synthesized
by condensation of tris(2-chloroethyl)amine with 4-hydroxyethylbenzoate followed by hydrolysis of the ester group. An aqueous
solution of Zn(NO3)2·6H2O reacts with the tetraethylammonium salt
of the podand at room temperature, to form a porous coordination
polymeric structure with infinite interlinked chains of Zn(II) metallocycles. An infinite water chain passes through the metallocycles
like a thread. The compound was characterized by X-ray
crystallography, X-ray powder diffraction, TGA, IR spectroscopy,
and elemental analysis.
