Abstract
A series of complexes of formula Ni(eta(5)-C5H5)(PR3)(SC6H4N=CHC6H4X-4') (R = Ph, Bu; X = F, Cl, Br, CH3, OH, H) has been isolated from the reactions of Ni(eta(5)-C5H5)(PPh3)Cl or the bromo derivative, the thiol Schiff base l igands, 4-HSC6H4N=CHC6H4X-4', and triethylamine. Preliminary thermal analys is data indicate that the PBu3 complexes could exhibit liquid crystalline b ehaviour. Electrochemistry of the PPh3 compounds gave irreversible redox co uples, in contrast to the quasi-reversibility of the PBu3 compounds.
