O.N.Kadkin, Yu.G.Galyametdinov, A.Rakhmatullin, 'Liquid-crystalline CuII and PdII complexes with nonmesogenic ferrocene-containing β-aminovinyl ketone', Russ. Chem. Bull. 48 379-381 (1999) doi:10.1007/bf02494570
New liquid-crystalline heteropolynuclear complexes L2M (M=Cu2+ (2a), Pd2+ (2b)) were synthesized by the reactions of C5H5FeC5H4−C6H4NH−C2H2−(CO)−C6H4OC12H25 (1, LH) with copper(ii) and palladium(ii) acetates. Compound2b was found to possess monotropic nematic and smectic phases;2a exhibits the monotropic nematic phase and a phenomenon of “double melting”. The compositions and structures of compounds1 and2a,b were established by elemental analysis,1H and13C NMR, ESR, and IR spectroscopy.
