摘要：

Three new nickel(II) complexes of 1-alkyl-2-phenyl asymmetrically substituted dithiolenes [Ni(SCR1=CR2S)2] (R1 = Ph; R2 = Bu(n), cyclopentylmethyl or 4-pentylcyclohexyl) have been prepared and their electrochemical properties and near-IR spectra studied. The crystal structures of the complexes in which R2 = Bu(n) or cyclopentylmethyl have been determined. The presence of bulky substituents adjacent to the ring has no affect upon the electrochemical or near-infrared properties. Third-order non-linear optical coefficients were measured by degenerate four-wave mixing.
