The tetranuclear Zn(II) complex, [{ZnL(mu-OAc) Zn(CH3CH2CH2OH)}(2)], derived from an asymmetrical Salamo-type chelate ligand H3L (5-methoxy-6'-hydroxy-2,2'-[ethanedioxybis(nitrilomethylidyne)] diphenol) has been synthesized and structurally characterized by elemental analysis, IR spectrum, X-ray crystallography, UV/Vis and fluorescence spectra. The structure is made up of four Zn(II) atoms, mu(2)-coordinated acetate ions and two coordinated n-propanol molecules, and forms an infinite one-dimensional supramolecular structure via intermolecular C-H center dot center dot center dot pi interactions. The four Zn(II) atoms are penta-coordinated and show slightly distorted trigonal bipyramidal and tetragonal pyramidal symmetries.
