The structure of the title compound, aqua[mu-(N-1-carboxylatomethylguanidino)oxidoacetato](mu-guanidinoacetic acid)dicopper(II) nitrate dihydrate, [Cu-2(C5H6N3O5)(C3H7N3O2)-(H2O)]NO3.2H(2)O, contains two enantiomers of the dicopper(II) complex cation that comprise water, neutral zwitterionic guanidinoacetic acid and the trianion of (N-1-carboxymethylguanidino)hydroxyacetic acid as ligands. Extensive hydrogen bonding creates three-dimensional connectivity but is largely confined to layers that each contain both cation enantiomers. These layers are related to one another by crystallographic symmetry and are therefore identical in composition and connectivity.
