Two new copper coordination complexes, [Cu(PI)(OX)(H2O)]·H2O (1) and [Cu(PI)(fum)(H2O)]·H2O (2) [PI?=?2-(2-pyridyl) imidazoline, OX2?/sup>?=?dianion of oxalic acid and fum2?/sup>?=?dianion of fumaric acid], were synthesized by interface diffusion method based on Cu(II) ions, PI ligands and aliphatic dicarboxylic acids. Complex 1 is a mononuclear complex which spreads into a 3D (4,9)-connected supramolecular network via hydrogen bond interactions, while complex 2 features a 1D zigzag chain with two different orientations. These two compounds are characterized by single crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, infrared spectra, and thermogravimetric analyses.
