title: A one-dimensional coordination polymer created via in situ ligand synthesis involving C-N bond formation.
abstract: The novel cadmium complex catena-poly[cadmium(II)-μ3-{2-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]butanedioato}], [Cd(C12H9N3O4)]n, has been prepared by the conjugate addition reaction of 2-(1H-pyrazol-3-yl)pyridine to fumaric acid in the presence of Cd(OAc)2·3H2O (OAc is acetate) at 413 K. Single-crystal X-ray diffraction analysis reveals that the complex consists of one-dimensional ladders constructed from [Cd2(COO)2] dimeric subunits. A combination of hydrogen bonding and π-π stacking interactions extend the one-dimensional ladders into a three-dimensional supramolecular architecture.
