Abstract
New liquid-crystalline heteropolynuclear complexes L2M (M = Cu2+ (2a), Pd2 (2b)) were synthesized by the reactions of C5H5FeC5H4-C6H4NH-C2H2-(CO)-C6H 4OC12H25 (1, LH) with copper(II) and palladium(II) acetates. Compound 2b wa s found to possess monotropic nematic and smectic phases; 2a exhibits the m onotropic nematic phase and a phenomenon of "double melting." The compositi ons and structures of compounds 1 and 2a,b were established by elemental an alysis, H-1 and C-13 NMR, ESR, and IR spectroscopy.
