| Summary: | There are two independent molecules in the asymmetric unit
of the title compound, C16H17NO4, with similar conformations
but some differences in their bond angles. Each molecule
adopts a trans configuration with respect to the methylidene
C N bond and is twisted with a dihedral angle between the
two substituted benzene rings of 80.52 (7)� in one molecule
and 83.53 (7)� in the other. All methoxy groups are
approximately coplanar with the attached benzene rings, with
Cmethyl—O—C—C torsion angles ranging from �6.7 (2) to
5.07 (19)�. In the crystal, independent molecules are linked
together by O—H� � �N and O—H� � �O hydrogen bonds and a
�–� interaction [centroid–centroid distance of 3.6030 (9) A ° ],
forming a dimer. The dimers are further linked by weak C—
H� � �O interactions and another �–� interaction [centroid–
centroid distance of 3.9452 (9) A ° ] into layers lying parallel to
the ab plane. |
