Abstract: The title racemic compound, [Cu(C₁₂H₁₁NO₅)(C₄H₆N₂)], adopts a square-pyramidal Cu^II coordination with the tridentate N-salicylideneglutamate Schiff base dianion and the 2-methylimidazole ligand in the basal plane. The apex of the pyramid is occupied by a carboxylic acid O atom from the neighbouring chelate at a distance of 2.479  (4)  Å, leading to infinite one-dimensional chains along the crystallographic a axis. Strong N-HO and O-HO hydrogen bonds form a helix parallel to the c axis. The electronic structure of the title compound has also been investigated by the B3LYP method.
