Indian Institute of Science, Bangalore-560 012 University of Basel,Basel, Switzerland Manuscriptreceived27February 1991 Results on the studiesof interactions ofmonovalent metal ions suchas Li+ and Ag+in LiCIO4 , LiBF4 and AgNO2withligands like acetonitrile,dimethyl sulphoxide. pyridine and acetone in thermotropic liquid crystals are reported They indicate the formation ofmetal ion ligand and metal ion-liquid crystal complexes. At least two types of complexes for each metal ion-ligand have been detected One ofthese is tetrahedral, providing isotropic-like' spectra intheliquid Crystalline media. |
