Abstract

The new liquid crystalline heteronuclear complexes Cu(II) 1a and Pd(II) 1bwith a nonmesogenic ferrocene-containing beta-enaminoketone L-1 of the formula C5H5FeC5H4-C6H4-NH-H-2(2)-(CO)-C6H4OC12H25, showing monotropic nematicand smectic A phases, are studied. The ortho-palladated Cl-bridged dimericcomplex 3 with a non-mesogenic ferrocene-containing Schiff's base L-2 of the formula C5H5FeC5H4-C6H4-N=CH-C6H4OC10H21, forming a stable smectic A phase, has been synthesized. The novel mixed-ligand heteronuclear complexes 4-7 have been obtained by treatment of the ortho-palladated complex 3 with appropriate ligands. Some of the resulting products exhibit the rather low-melting (below 100 degrees C) smectic A phases. Structures of the compounds are studied by elemental analysis, H-1 and C-13 NMR, and ESR spectroscopies.
