Abstract
- Two trinuclear CoII and ZnII complexes, [(CoL)2(OAc)2Co] and [(ZnL)2(OAc)2Zn], with an asymmetric Salen-type bisoxime ligand [H2L = 4-( N, N-diethylamine)-2,2′-[ethylenediyldioxybis(nitrilomethylidyne)]diphenol] were synthesized and characterized by elemental analyses, IR, UV/Vis, and fluorescent spectroscopy. The crystal structures of the CoII and ZnII complexes were determined by single-crystal X-ray diffraction methods. The CoII atom is pentacoodinated by N2O2 donor atoms from the (L)2- unit and one oxygen atom from the coordinated acetate ion, resulting in a trigonal bipyramid arrangement. With the help of intermolecular hydrogen bonding C-H ···O and C-H ···π interactions, a self-assembled continual zigzag chain-like supramolecular structure is formed. The ZnII atom is pentacoodinated by N2O2 donor atoms from the (L)2- unit and one oxygen atom from the coordinated acetate ion, resulting in an almost regular trigonal bipyramid arrangement. A self-assembled continual 1D supramolecular chain-like structure is formed by intermolecular hydrogen bonding C-H ···O and C-H ···π interactions. Additionally, the photophysical properties of the CoII and ZnII complexes were discussed. [ABSTRACT FROM AUTHOR]
