Název v původním jazyce

The Isomers of Gadolinium Scandium Nitride Clusterfullerenes GdxSc3-xN@C80 (x=1, 2) and Their Influence on Cluster Structure

Popis výsledku v původním jazyce

The isomers of gadolinium scandium mixed-metal nitride clusterfullerenes GdxSc3xN@C80 [x=2 (1, 4);x=1 (2, 5)] have been synthesized by the "reactive gas atmosphere" method and isolated facilely by recycling HPLC. The yield of GdxSc3_xN@C80 (I,II) (x=1, 2) relative to the homogenous clusterfullerenes Sc3N@C80 [I (3), II (6)] was determined. According to the UV/Vis/NIR spectroscopic data, 1, 2, 4, and 5 are all stable fullerenes with large optical gaps. Fullerene 1 has greater similarity to Gd3N@C80 (I) and 2 seems to resemble Sc3N@C80 (I). The quite similar overall absorption features of 4 and 5 suggest pronounced similarity in electronic structure. Vibrational spectroscopic studies led to the assignment of the cage symmetries of GdxSc3_xN@C80 (I, II),that is, Ih for 1, 2 and D5h for 4, 5. The cluster?cage interactions in GdxSc3_xN@C80 (I, II) were analyzed by means of the lowenergy Raman lines.
