ABSTRACT A mono‐salamo‐type ligand H 2 L was prepared to utilize 3‐methoxysalicylaldehyde and a semi‐salamo‐type compound, its novel trinuclear Ni(II) cluster with two significantly various configurations in the solid state obtained by reaction of ions. The structure validated x‐ray technique, ions exhibited hexa‐coordinated twisted octahedrons. Its structural formula is [Ni 3 (L) ( μ ‐Cl) (EtOH) ]. Chloride have also successfully double bridged participate coordination, play critical impact configuration's stability charge balance. Two solvent ethanol molecules are participated coordination. coordination ratio metal ion verified be 2:3 UV–Vis absorption titration spectroscopy. HOMO LUMO energies frontline molecular orbitals complex were analyzed DFT calculations, energy gap value 4.29 eV, that 0.72 eV. combined decreased produced more active complex. Furthermore, Hirshfeld surface analysis visualizes weak interactions crystalline molecules, these abundant an especially effect supramolecular self‐assembling. fluorescent researches proclaimed fluorescence intensity compared ligand, suggesting this greater promise for sensing.

Salamo‐type ligand H 2 L was designed and synthesized reacted with Cu (II) Zn acetate, respectively, to obtain two binuclear complexes: [Cu (L) ]·2CH 3 OH ( 1 ) [Zn ] having the same coordination number but distinct geometries. Complex is a complex containing crystalline ethanol molecules, where atoms are surrounded by utterly deprotonated 2− parts, forming slightly twisted tetragonal pyramidal configurations of pentacoordinate. In , parts surround atoms, pentadentate triangular bipyramidal configurations. The complexes were elucidated via IR analyses ultraviolet spectroscopy. Using DFT theoretical calculation, MEPs, IRI, Hirshfeld surface analysis investigate further molecular interactions reaction sites. Ultimately, fluorescence characteristics its discussed.
