Abstract
Reaction of NiCl2. 6H(2)O and Na-2[mnt] (mnt = maleonitriledithiolate) in C H3OH at room temperature leads to Ni(II) dithiolato complex [Ni(mnt)(2)](2- ). An oxidation process of [Ni(mnt)(2)](2-) affords [{Ni(mnt)(2)}(2)](2-) a nd yields solid crystalline product [Na-2(benzo-15-crown-5)(3)(H2O)(2)][{Ni (mnt)(2)}(2)] (1) in the presence of benzo-15-crown-5. X-ray diffraction an alyses revealed that in solid state the dianions of 1 pack as columns and t he counter ions are discrete disodium triple-decker dications. A non-linear absorption coefficient beta of 2.4 cm GW (- 1) was recorded at 1069 nm for 1 in acetonitrile solution with a concentration of 1.0 x 10(-4) mol 1(-1). (C) 2000 Elsevier Science S.A.
