A series of complexes of formula Ni(η5-C5H5)(PR3)(SC6H4NCHC6H4X-4â²) (R = Ph, Bu; X = F, Cl, Br, CH3, OH, H) has been isolated from the reactions of Ni(η5-C5H5)(PPh3)Cl or the bromo derivative, the thiol Schiff base ligands, 4-HSC6H4NCHC6H4X-4â², and triethylamine. Preliminary thermal analysis data indicate that the PBu3 complexes could exhibit liquid crystalline behaviour. Electrochemistry of the PPh3 compounds gave irreversible redox couples, in contrast to the quasi-reversibility of the PBu3 compounds.
分离出一系列式 Ni(β5-C5H5)(PR3)(SC6H4NCHC6H4X-4â²) (R=Ph, Bu; X=F, Cl, Br, CH3, OH, H) 的配合物由 Ni(β5-C5H5)(PPh3)Cl 或溴代衍生物、硫醇希夫碱配体、4-HSC6H4NCHC6H4X-4â² 和三乙胺的反应得到。初步热分析数据表明 PBu3 配合物可能表现出液晶行为。 PPh3 化合物的电化学产生不可逆的氧化还原对,与 PBu3 化合物的准可逆性相反。
