| 摘 要： | Two novel supramolecular complexes, Cu（bopapa）（mal）]·H2O·CH3OH （1） and {Cu（bopapap）]（Hmal）2}·2H2O （2） bpapa = bis-6-（2-pyridylamino）pyrid-2-yl]amine, bpapap = 2,6-bis-6-（pyrid-2-ylamino）pyrid-2-ylamino]- pyridine, mal=maleate dianion] were rationally designed and synthesized based on flexible multidentate ligands and copper（Ⅱ） maleate. Complexes 1 and 2 were all characterized by elemental analysis, spectroscopic techniques, thermal analysis and single crystal X-ray diffraction analysis. Complex 1 is of an infinite 3-D supramolecular framework constructed by 2-D sheets to contain 1-D helical chains formed by intermolecular hydrogen bond inter- actions between the non-coordinated oxygen atoms from maleate and nitrogen atoms from amino groups of bpapa. Complex 2 also takes a 3-D supramolecular structure, which is built from 2-D rhombic sheets produced by sequential dimer units. Interestingly, three pairs of symmetrical hydrogen bonds generate these dimer units.

| Abstract: | Two novel supramolecular complexes, Cu(bpapa)(mal)]·H2O·CH3OH ( 1 ) and {Cu(bpapap)](Hmal)2}·2H2O ( 2 ) bpapa=bis‐6‐(2‐pyridylamino)pyrid‐2‐yl]amine, bpapap=2,6‐bis‐6‐(pyrid‐2‐ylamino)pyrid‐2‐ylamino]‐pyridine, mal=maleate dianion] were rationally designed and synthesized based on flexible multidentate ligands and copper(II) maleate. Complexes 1 and 2 were all characterized by elemental analysis, spectroscopic techniques, thermal analysis and single crystal X‐ray diffraction analysis. Complex 1 is of an infinite 3‐D supramolecular framework constructed by 2‐D sheets to contain 1‐D helical chains formed by intermolecular hydrogen bond interactions between the non‐coordinated oxygen atoms from maleate and nitrogen atoms from amino groups of bpapa. Complex 2 also takes a 3‐D supramolecular structure, which is built from 2‐D rhombic sheets produced by sequential dimer units. Interestingly, three pairs of symmetrical hydrogen bonds generate these dimer units. |
