In the title compound, [Cu(C16H19BrNO4)(2)]center dot 2H(2)O, the Cu-II ion resides on an inversion centre and is coordinated by two O and two N atoms from two enantiomeric 5-(4-bromophenyl)-4-(tert-butoxycarbonyl)pyrrolidine-2-carboxylate ligands in a distorted square-planar geometry. The relative stereochemistry of the three stereogenic C atoms in each ligand has been determined. In the crystal, intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds link the molecules into layers parallel to the bc plane. The crystal studied was twinned by pseudomerohedry with twin fractions of 0.719 (3) and 0.281 (3).
