N2 - Crystallography reveals the rotomer in the salt isolated from EtOH solution has an anti disposition of the OH and imine-NH hydrogen atoms while that from EtOCH2CH2OH solution has a syn disposition. Both molecules have an E configuration about the C=N bond and are essentially planar (dihedral angles between aromatic groups = 2.4 (3)° and 6.42 (9)°, respectively). The anti-rotomer crystallizes in the monoclinic space group P21/n with a = 10.8795 (10) Å, b = 10.7730 (11) Å, c = 13.1257 (7) Å, λ = 104.806 (5)°, and Z = 4. The syn-rotomer crystallizes in the monoclinic space group C2/c with a = 14.4610 (5) Å, b = 11.3073 (5) Å, c = 17.8849 (7) Å, β = 91.904 (2)°, and Z = 8.
