Examining the role of molecular and crystallographic symmetry in isomorphism: a series of centrosymmetric “bridge-flipped” trifluoromethyl-substituted bis-benzylideneanilines

To determine if location of bridge-flipped isomers on crystallographic inversion centers promotes their isomorphism, a study of molecularly centrosymmetric bis-benzylideneanilines has identified a new isomorphous trifluoromethyl-substituted pair.
