Abstract
- Two solvent-induced bis(phenoxo)-acetate-bridged binuclear Ni(II) complexes, [Ni<subscript>2</subscript>(L)(µ-OAc)(CH<subscript>3</subscript>OH)] (1) and [Ni<subscript>2</subscript>(L)(µ-OAc)(H<subscript>2</subscript>O)] (2), were synthesized with a bis(salamo)-like ligand H<subscript>3</subscript>L and Ni(OAc)<subscript>2</subscript>·4H<subscript>2</subscript>O in two different alcohol solvents (methanol and ethanol). Complexes 1 and 2 were described by elemental analyses, single crystal X-ray diffraction, IR spectra, UV–vis spectra and fluorescence spectra. Complexes 1 and 2 have analogous crystal structures, but the non-covalent interactions are distinct. The one-dimensional chain of 1 is formed by π–π interactions, and the three-dimensional supramolecular network structure of 2 is formed by intermolecular hydrogen bonding interactions. In addition, fluorescence experiments indicated that the fluorescence of 1 and 2 undergoe a significant quenching compared to H<subscript>3</subscript>L. Intermolecular forces were investigated using Hirshfeld surface analysis. DFT calculations showed that 1 and 2 have high chemical reactivity and low kinetic stability. [ABSTRACT FROM AUTHOR]
