TODO - Employment of di-2-pyridyl ketone and poly-carboxylates in Cu-II
chemistry afforded four complex hydrogen-bonded frameworks, one
one-dimensional (1D), one 2D and three 3D coordination polymers.
Di-2-pyridyl ketone underwent several metal-assisted transformations to
yield three Cu-II structural units which, in combination with the
poly-carboxylate anions of the trimesic, isophthalic,
5-hydroxy-isophthalic and pyromellitic acids, provided access to
extended frameworks by dative or hydrogen bonds. All nine complex
frameworks were realized in terms of their topological analysis. The 3D
and the 2D polymers consisted of [Cu-2] dimers and were found to be
dominated by ferromagnetic interactions. The origin of the ferromagnetic
coupling was attributed to the counter complementarity of the
simultaneous alkoxo/syn, syn-carboxylate bridges within the dimers.
