Abstract
- Centrosymmetric homopolynuclear Cu(II) and Co(II) chelated complexes, [Cu<subscript>2</subscript>(L)(H<subscript>2</subscript>O)<subscript>2</subscript>] (1) and [Co<subscript>4</subscript>(L)(μ-OAc)<subscript>2</subscript>(CH<subscript>3</subscript>OH)<subscript>4</subscript>(OA<subscript>C</subscript>)<subscript>2</subscript>]⋅2CH<subscript>2</subscript>Cl<subscript>2</subscript> (2), were synthesized using a new symmetrical methoxy-disubstituted bis(salamo)-type ligand, H<subscript>4</subscript>L, with Cu(II) and Co(II) salts in organic solvents. Complexes 1 and 2 were structurally characterized by single-crystal X-ray crystallography. The results indicated that 1 is a five-coordinate dinuclear structure containing Cu(II) and 2 is a tetranuclear Co(II) complex with two distinct six-coordinate environments. Furthermore, 1 and 2 pack into three-dimensional and two-dimensional extended networks, respectively. The UV–Vis spectra, IR spectra, and Hirshfeld surface analyses of the complexes were carried out to further characterize the coordination between H<subscript>4</subscript>L and the metal(II) ions. Fluorescence methods were used to interrogate the coordination, where changes in emission with varied amounts of ligand supported solution-phase coordination ratios of H<subscript>4</subscript>L with Cu(II) ion of 1:2 and with Co(II) ion of 1:4, respectively.
