The reaction between 2-N-tosylamino-(2'-tosylaminobenzal)aniline (H2L), 2-aminopyridine (L'), and a zero-valent metal (M) in methanol results in the electrochemical synthesis of the ML (.) L' adducts [M = Ni (I) or Co]. The copper complex obtained under the same conditions has the composition CuL (.) CH3OH (II). The structures of the compounds obtained are investigated using IR spectroscopy, FAB(+) mass spectrometry, and magnetochemistry. The crystal structures of compounds I and II are determined by X-ray diffraction. In molecules I and II, the metal atoms are coordinated by three N atoms of the L ligand. The mean M-N distances are 1.97 in I and 1.89 Angstrom in II. The fourth site in the coordination sphere of the central atom in I and II is occupied by the endocyclic N atom of the L' ligand (Ni-N, 2.01 Angstrom) and the O atom of the methanol molecule (Cu-O, 2.06 Angstrom), respectively. The coordination polyhedra of the metal atoms in I and II are complemented by the O atom of the tosyl fragment of the L ligand (Ni-O, 2.41 Angstrom in I; Cu-O, 2.64 Angstrom in II).
