    • Shorter H⋯acceptor distances do not necessarily correlate with stronger hydrogen bonds because of crystal packing effects, orientation angles, and other intermolecular interactions.

    • Strictly speaking, the mean hydrogen-bond distance of 4 is equal (within an error bound of 4σ) to the average distance of 2.16(6) Å for the seven compounds listed in Table 2.

    • note
    • The same polymorph of 4 was obtained by slow evaporation of a solution of the Schiff base in ethanol or diffusion of hexane into a dichloromethane solution of the compound, which suggests that the C2/c polymorph is thermodynamically preferred. Phase changes and polymorphism may well not be energetically feasible in this system.
