The discovery of a new isomer of the endohedral metallofullerene Sc
b>3b>N@C
b>80b> is reported.
13C la
beled (
border=0 SRC=/images/glyphs/BQ1.GIF>9 % ) Sc
b>3b>N@C
b>80b> has
been synthesized and has
been characterized
by HPLC, mass spectroscopy and
13C NMR data. The
13C NMR spectrum shows six peaks with a 1:2:2:1:1:1 ratio that are assigned to the
Db>5hb> isomer. The results of theoretical calculations are also reported for the
Ib>hb> and
Db>5hb> isomers of Sc
b>3b>N@C
b>80b>.
