Metastable complexes of some d- and f-block metals with mesogenic cyanobiphenyls

  • 73 Accesses

  • 6 Citations

Abstract

Formation of metastable complexes with different metal to mesogenic ligand ratio (M/L = 1/2 and 1/1) has been shown by IR–, UV–Vis, ESR-spectroscopic techniques for low temperature co-condensation of some d- and f-block transition metals (Ag, Cu, Eu, Sm) and mesogenic derivatives of cyanobiphenyls. The Quantum chemistry calculations have been carried out to study equilibrium structures of complexes. Biligand complex models with one and two metal atoms and antiparallel disposition of two ligand molecules are considered. Relative spectral shifts and relative thermal stability of complexes are discussed.
