Rare homodinuclear Co (II) complex [Co 2 (L)NO 3 ] ( 1 ) and helical centrosymmetric homotetranuclear Cu (II) complex [Cu 4 (L) 2 (H 2 O) 2 ]·2ClO 4 ( 2 ), have been synthesized by a newly explored bis (salamo)‐like tetraoxime ligand (H 3 L) with Co (NO 3 ) 2 ·6H 2 O and Cu (ClO 4 ) 2 ·6H 2 O, 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 N 2 O 4 and N 2 O 3 coordination spheres, and distorted octahedral (Co1) and slightly distorted triangular bipyramidal (Co2) geometries, while Cu (II) atoms in complex 2 have also two different N 2 O 4 (Cu1) and N 2 O 3 (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.
