“…4) are due to two isotopes of silver atoms: 107 Ag (J = 1/2) and 109 Ag (J = 1/2). The magnetic resonance parameters of these signals obtained via computer treatment of the experimental spectra are characteristic for silver p-complexes: 107 Ag (J = 1/2) b 109 Ag (J = 1/2), g xx = 2.005, g yy = 1.999, g zz = 1.995; A xx = 693, A yy = 656, A zz = 575 and A xx = 603, A yy = 570, A zz = 508 [20]. Comparison of the isotropic splitting constants for complexes with data for silver atoms isolated in hydrocarbon matrix (A(Ag 107 ) = 611 G and A(Ag 109 ) = 705.4 G) using common procedure allowed to estimate the electron spin density on silver in Ag-5CB as q M = 0.89.…”

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.
