| Abstract: | Rare homodinuclear Co (II) complex [Co2(L)NO3] ( 1 ) and helical centrosymmetric homotetranuclear Cu (II) complex [Cu4(L)2(H2O)2]·2ClO4 ( 2 ), have been synthesized by a newly explored bis (salamo)-like tetraoxime ligand (H3L) with Co (NO3)2·6H2O and Cu (ClO4)2·6H2O, respectively, and characterized by elemental analyses, IR, UV–Vis spectroscopy and single crystal X-ray crystallography. X-ray crystallographic studies indicate that the two Co (II) atoms (Co1 and Co2) in complex 1 have different N2O4 and N2O3 coordination spheres, and distorted octahedral (Co1) and slightly distorted triangular bipyramidal (Co2) geometries, while Cu (II) atoms in complex 2 have also two different N2O4 (Cu1) and N2O3 (Cu2) coordination environments, and complex 2 forms a helical centrosymmetric molecule. In addition, supramolecular interactions, Hirshfeld surfaces analyses, antibacterial and fluorescence properties were also investigated in detail. |
