1,3-Bis{(E)-[4-(di-methyl-amino)-benzyl-idene]amino}-propan-2-ol: chain structure formation via an O-H?N hydrogen bond.

ABSTRACT: The asymmetric unit of the title compound, C₂₁H₂₈N₄O, consists of two unique mol-ecules linked by an O-H?N hydrogen bond. The conformation of both C=N bonds is E and the azomethine functional groups lie close to the plane of their associated benzene rings in each of the independent mol-ecules. The dihedral angles between the two benzene rings are 83.14?(4) and 75.45?(4)°. The plane of the one of the N(CH₃)₂ units is twisted away from the benzene ring by 18.8?(2)°, indicating loss of conjugation between the lone electron pair and the benzene ring. In the crystal structure, O-H?N hydrogen bonds together with C-H?O hydrogen bonds link neighbouring supra-molecular dimers into a three-dimensional network.
