Three mixed ligand nickel(II) complexes were synthesized and characterized by UV-visible, IR, MS and elemental analysis. Their off-resonant third-order nonlinear optical properties were measured using femtosecond laser and degenerate four-wave mixing technique. The third-order nonlinear optical susceptibilities chi((3)) were 3.20-3.51 x 10(-13) esu. The nonlinear refractive indexes n(2) were 5.89-6.45 x 10(-12) esu. The second-order hyperpolarizabilities gamma of the molecules were 3.20-3.50 x 10(-31) esu. The response times were 55-81 fs. The results show that these complexes have potential nonlinear optical applications.
