Novel infinite three-dimensional network of neutral fullerene molecules in (C60)8(twin-TDAS)6

The crystal structure of (C60)8(twin-TDAS)6 [twin-TDAS = C4S6N4 = 3,3',4,4'-tetrathiobis(1,2,5-thiadiazole)] has been redetermined at low temperature in the correct space group [I23, a = 18.849 (1) A]. Structural analysis reveals a novel three-dimensional close-contact network of C60 molecules with tetrahedral holes similar to pristine C60.
