【 摘 要 】

The complexes [Ni(L)(INT)₂]·5H₂O (1) and [Cu(L)(H₂O)](Cl)(INT)·3H₂O (2) (L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,0^1.18 ,0^7.12 ]docosane, INT = isonicotinate) have been prepared and characterized by X-ray crystallography, electronic absorption, and cyclic voltammetry. The crystal structure of 1 reveals an axially elongated octahedral geometry with two axial isonicotinate ligands. The electronic spectra, magnetic moment, and redox potentials of 1 also show a high-spin octahedral geometry. However, 2 shows that the coordination environment around the copper atom is a distorted square-pyramid with an axial water molecule. The spectra and electrochemical behaviors of 2 are also discussed.
