The third-order nonlinear susceptibility, {chi}{sup (3)}, for a series of complexes of 3,5-ditertbutyl-o-benzoquinone (dbsq), (M(dbsq){sub 2} where M = Pd or Pt), o-mercaptophenol (mp), ((TBA)[Ni(mp){sub 2}]), or 1,3-dithiol-2-thione-4,5-dithiol (dmit), ((TBA)[M(dmit){sub 2}] where M = Ni or Pd), have been measured in CH{sub 2}Cl{sub 2} solution by retroreflection DFWM technique at 1064 mn. The results indicate large {chi}{sup (3)} values of the order of 10{sup {minus}11} esu at concentration levels of 10{sup 18} molecules/cm{sup 3}. These values are up to two orders higher than those found for other sulphur donor dithiolenes and nitrogen donor ligand systems, although the linear absorption is also higher.
