The title compound, [Cu(C10H9NO3)(C3H4N2)]2, adopts a square-pyramidal copper(II) coordination with three donor atoms of the N-salicylidene-rac-alaninato Schiff base dianion and the imidazole ligand bound in the basal plane. The axial position is occupied by an oxygen ligand from an adjacent chelate at an apical distance of 2.500 (3) Å, forming a centrosymmetric dimer. These dimers are connected through hydrogen bonding to form chains parallel to [010]. All copper polyhedra belonging to one chain are oriented parallel to each other, whereas between the two types of chains they are tilted at an angle 2γ of 38.9 (2)°.
