Crystal structure of ethyl 2-{2-[(1Z)-1-hy-droxy-3-(4-nitro-phen-yl)-3-oxoprop-1-en-1-yl]phen-oxy}acetate.

ABSTRACT: The title compound, C19H17NO7, crystallized in a ratio of about 6:4 of the two possible keto-enol forms. This was observed as disorder over the central C3H2O2 unit. The dihedral angle between the rings is 8.2 (2)°.The mol-ecules pack by C-H⋯O interactions in a layered fashion parallel to (-104).
