The title compound, [Cu-2(NO3)(2) (C3H7N3O2)(4)], forms a centrosymmetric dimer, with the two Cu2+ ions separated by 2.6525 (6) Angstrom. The asymmetric unit contains a Cu atom coordinated to two guanidinoacetic acid ligands (via one carboxylate O atom from each ligand) and to a nitrate group. The inversion centre in P (1) over bar generates the entire molecule, in which each Cu atom is coordinated to four carboxylate and to one nitrate O atom; ignoring the Cu-Cu separation, the geometry about each Cu atom is square pyramidal. The amino acid ligand is in the zwitterionic form. Strong N-H...O hydrogen bonds lead to a three-dimensional supramolecular structure, in which the N...O distances are in the range 2.931 (4)-3.278 (3) Angstrom, with N-H...O angles ranging from 128 to 170degrees.
