Figure 1
Thermal ellipsoid plots drawn at the 50% probability level: (a) 2CN2T, (b) 2CN3T, (c) 2CN4T, (d) 3CN2T, (e) 3CN3T, (f) 3CN4T, (g) 4CN2T, (h) 4CN3T, (i) 4CN4T.F1, and (j) 4CN4T.F2 (F1 and F2 are two polymorphs of 4CN4T). The –CF3 group exhibits rotational disorder, the occupancy ratio being 0.679 (13): 0.321 (13) in 3CN3T and 0.538 (18):0.462 (18); and 0.712 (20):0.288 (20) for M1 (magenta color) and M2 (dark green) in 4CN3T, respectively. Atoms are coloured magenta, dark green, and violet color in molecules M1, M2 and M3, respectively, in the asymmetric unit. Dotted lines depict intermolecular interactions in the asymmetric unit.
