| Abstract: Two Cu(Ⅱ) and Ni(Ⅱ) complexes,[Cu(L1)2]·(1,4-dioxane) (1) (HL1=8-(((4-(1-((benzyloxy) imino) ethyl) phenyl) imino) methyl)-7-hydroxy-4-methyl-2H-chromen-2-one) and[Ni(L2)2] (2) (HLL2=1-(4-(((2-hydroxynaphthalen-1-yl) methylene) amino) phenyl) ethanone O-benzyloxime), have been synthesized and characterized by elemental analyses, IR spectra, UV-Vis spectra, fluorescence spectra and X-ray single crystal diffraction method. X-ray crystallographic analysis shows that the Cu(Ⅱ) and Ni(Ⅱ) ions are all four-coordinated in a trans-N2O2 slightly distorted square-planar geometry by two hydroxy O and two imine N atoms from two N,O-bidentate Schiff base ligands. Moreover, complex 1 links some other molecules into an infinite 3D supramolecular structure by intermolecular hydrogen bonds and π…π stacking interactions, while complex 2 forms 1D infinite chain via intermolecular π…π stacking interactions. Furthermore, the fluorescence property of HL1, HLL2 and their metal complexes 1 and 2 are discussed. |
