In the present study, the results of investigation of physical properties of heterofulleridesA3−xMxC60(A=K, Rb, Cs, M=Be, Mg, Ca, Al, Fe, Tl,x=1,2); as well asRbCsTlC60,KCsTlC60, andKMg2C60are described. All of the fullerides were synthesized by the exchange reactions of alkaline fullerides with anhydrous metal halides. Superconductivity was found inRbCsTlC60andKCsTlC60.

Reaction of the dicopper (II) complex of the binucleating ligand 5,5- bis (4-amino-2-azabutyl)-3,7-diazanonane-1,9-diamine with nitroethane and formaldehyde in water gives the respective macrobicyclic and macromonocyclic binucleating ligands 7,21-dimethyl-7,21-dinitro-2,5,9,12,16,19,23,26-octaazaspiro[13.13] heptacosane and 6,6-bis(4- amino-2-azabutyl)-13-methyl-13-nitro-1,4,8,11-tetraazacyclotetradecane , both as their dicopper (II) complexes. Similarly, condensation of the dicopper (II) complex of 5,5-bis(4-amino- 2-thiabutyl)-3,7-dithianonane-1,9-diamine with nitroethane and formaldehyde results in the binucleating macrobicycle 7,21-dimethyl- 7,21-dinitro-2,12,16,26-tetrathia-5,9,19,23-tetraazaspiro[13.13]-heptacosane. Physical properties of all complexes are reported and comparisons with mononuclear relatives are made. Structural parameters derived from electron paramagnetic resonance spectra are discussed.

AbstractUnusual physical properties of ionic liquids (ILs) can be implemented in many different applications and are very sensitive to the structure of IL. In this work we investigate the spin dynamics of probe molecule Zn tetraphenylporphyrin (ZnTPP) dissolved in a series of ILs using time-resolved electron paramagnetic resonance (TR EPR). We compare the TR EPR characteristics in C2-methylated imidazolium-based ILs [bmmim]BF
