Two new trinuclear Ni(II) complexes, [{Ni(L)(DMF)(μ-OAc)}2Ni] (1) and [{Ni(L)(EtOH)(μ-OAc)}2Ni]·2CH2Cl2 (2), have been successfully synthesized from a new asymmetric salamo-based hexa-dentate chelating ligand (H2L) and Ni(OAc)2·4H2O, and characterized by elemental analysis, IR and UV-Vis spectra, and X-ray crystallography. The binding ratio of H2L and Ni(II) ion has been confirmed by UV-Vis titration. All Ni(II) atoms are hexa-coordinated, and the complexes have octahedral configuration, though with difference in the solvent molecules (DMF/EtOH) involved in the coordination, composition of the hydrogen bond and chemical stability. This conclusion is confirmed by Hirshfeld surfaces analyses and Density Functional Theory (DFT). [ABSTRACT FROM AUTHOR]
