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.
