Dinuclear Ni(Ⅱ) and cubane-like Cu₄(μ₃-O)₄ cored tetranuclear Cu(Ⅱ) complexes, [Ni(L¹)(DMF)(H₂O)]₂ (1) (H₂L¹=3-((5-bromo-2-hydroxy-benzylidene)-amino)-4-hydroxy-benzopyran-2-one), [Cu₄(L²)₄]·DMF·CH₃OH·2H₂O (2) (H₂L²=4-hydroxy-3-((2-hydroxy-3-methoxy-benzylidene)-amino)-benzopyran-2-one) based on 3-amino-4-hydroxy-coumarin Schiff base ligands were synthesized and characterized by elemental analysis, IR, UV-Vis, emission spectra and X-ray single crystal diffraction analysis. The X-ray single crystal diffraction analysis results show that complex 1 has a binuclear structure composed of two metal ions and two ligand units, and complex 2 has a tetranuclear structure composed of four metal ions and four ligand units. Complex 1 crystallizes in monoclinic system, C2/c space group, whereas complex 2 crystallizes in tetragonal system, I4₁/a space group. The spatial configurations of the central metal Ni(Ⅱ) and Cu(Ⅱ) ions are all six-coordinated distorted octahedron in complexes 1 and 2, respectively. In addition, complex 1 forms a one-dimensional (1D) supramolecular chain through intermolecular hydrogen bonding, C-H…π and π…π stacking interactions, while complex 2 formed three-dimensional(3D) supramolecular network structure via intramolecular hydrogen bonding and π…π stacking interactions.
