Crystal structure of ethyl 2-{2-[(1Z)-1-hy­droxy-3-(4-nitro­phen­yl)-3-oxoprop-1-en-1-yl]phen­oxy}acetate

The title compound, C(19)H(17)NO(7), crystallized in a ratio of about 6:4 of the two possible keto–enol forms. This was observed as disorder over the central C(3)H(2)O(2) unit. The dihedral angle between the rings is 8.2 (2)°.The mol­ecules pack by C—H⋯O interactions in a layered fashion parallel to...

Sumario:The title compound, C(19)H(17)NO(7), crystallized in a ratio of about 6:4 of the two possible keto–enol forms. This was observed as disorder over the central C(3)H(2)O(2) unit. The dihedral angle between the rings is 8.2 (2)°.The mol­ecules pack by C—H⋯O interactions in a layered fashion parallel to (-104).
