Poly[(μ4-phenylphosphonato)zinc(II)]
The title two-dimensional coordination polymer, [Zn(C6H5PO3)]n, was
synthesized serendipitously by reacting a tetraphosphonate cavitand
Tiiii[C3H7, CH3, C6H5] and Zn(CH3COO)22H2O in a DMF/H2O mixture. The
basic conditions of the reaction cleaved the phosphonate bridges at the upper
rim of the cavitand, making them available for reaction with the zinc ions. The
coordination polymer can be described as an inorganic layer in which zinc
coordinates the oxygen atoms of the phosphonate groups in a distorted
tetrahedral environment, while the phenyl groups, which are statistically
disordered over two orientations, point up and down with respect to the layer.
The layers interact through van der Waals interactions. The crystal studied was
refined as a two-component twin
