A novel supramolecular Cu() complex [Cu-2(L-2)(2)] (H2L2 = 4-bromosalicylaldehyde O-(2-hydroxyethyl)oxime) is synthesized through the complexation of Cu(OAc)(2)H2O with an asymmetric salamo-type ligand 4-bromo-6-hydroxy-2,2-[ethylenedioxybis(nitrilomethylidyne)]diphenol (H3L1) and is structurally characterized by single crystal X-ray diffraction. The X-ray crystal structure of the Cu() complex reveals it to crystallize in the triclinic system,in which each Cu(II) atom is in a distorted square pyramidal geometry. The whole Cu() complex consists of a series of [Cu-2(L-2)(2)] units, forming an infinite 1D chain supramolecular structure. Meanwhile, the Cu(II) complex exhibits emission with the maximum emission wavelength (max) = 431 nm when excited at (ex) = 367 nm.
