【 摘 要 】

Assembly of diphenylphosphate (dpp) with Cu(II) salts in combination with the different Ndonor linkers, e.g., pentamethyldiethylenetriamine (pmdeta), bis-(3-aminopropyl)amine (bapa) and 4-Picolene (4-pic), yielded three new metal-organic coordination complexes, namely {[Cu(dpp)(pmdeta)]·ClO₄.H₂O}₂ (1), {[{[Cu(dpp)(bapa)H₂O]·ClO₄} (2) and [Cu(dpp)2(4-pic)₂]₂ (3) by stirring the constituent reactants at room temperature. Complexes 1–3 were characterized by single crystal X-ray diffraction analysis and were further characterized by elemental analysis, infrared spectroscopy (IR) and powder X-ray diffraction (PXRD) studies. Compound 1 exhibits a dimeric Cu(II) complex which forms a 1D supramolecular chain along the crystallographic c-axis by means of intermolecular π .. .π interactions. Compounds 2 and 3 form a monomeric and dimeric complex of Cu(II) respectively, which are further extended into a supramolecular 2D structure viaC-H..π interactions for 2 and a 3D structure for 3 with the help of both intermolecular C-H..π and π . . . π interactions for 3. In addition, the solid state UV-Vis spectra of compounds 1-3 and free dpp ligand have beeninvestigated at room temperature.
