Crystal structures of ethyl 6-(4-methyl-phen-yl)-4-oxo-4H-chromene-2-carboxyl-ate and ethyl 6-(4-fluoro-phen-yl)-4-oxo-4H-chromene-2-carboxyl-ate.

Project description:The crystal structures of two chromone derivatives, viz. ethyl 6-(4-methyl-phen-yl)-4-oxo-4H-chromene-2-carboxyl-ate, C19H16O4, (1), and ethyl 6-(4-fluoro-phen-yl)-4-oxo-4H-chromene-2-carboxyl-ate C18H13FO4, (2), have been determined: (1) crystallizes with two mol-ecules in the asymmetric unit. A comparison of the dihedral angles beween the mean planes of the central chromone core with those of the substituents, an ethyl ester moiety at the 2-position and a para-substituted phenyl ring at the 6-position shows that each mol-ecule differs significantly from the others, even the two independent mol-ecules (a and b) of (1). In all three mol-ecules, the carbonyl groups of the chromone and the carboxyl-ate are trans-related. The supra-molecular structure of (1) involves only weak C-H?? inter-actions between H atoms of the substituent phenyl group and the phenyl group, which link mol-ecules into a chain of alternating mol-ecules a and b, and weak ?-? stacking inter-actions between the chromone units. The packing in (2) involves C-H?O inter-actions, which form a network of two inter-secting ladders involving the carbonyl atom of the carboxyl-ate group as the acceptor for H atoms at the 7-position of the chromone ring and from an ortho-H atom of the exocyclic benzene ring. The carbonyl atom of the chromone acts as an acceptor from a meta-H atom of the exocyclic benzene ring. ?-? inter-actions stack the mol-ecules by unit translation along the a axis.

Project description:The title compound, C(19)H(14)O(4), was prepared by the reaction of 2-oxo-2H-chromene-3-acyl chloride with cinnamic alcohol.

In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link two mol-ecules into dimers, and ?-? stacking inter-actions between inversion-related rings of the coumarin groups [centroid-centroid distance 3.8380?(15)?Å with a slippage of 1.535?Å], which connect the dimers into columns extending along [010].

The crystal packing also features C-H?? inter-actions.

Project description:In the title compound, C23H20BrNO4, the pyran ring has a flattened boat conformation with the O and methine C atoms lying to one side of the plane [0.160?(5) and 0.256?(6)?Å, respectively] defined by the remaining atoms.

In addition to an intra-molecular N-H?O(ester carbon-yl) hydrogen bond, the ester carbonyl O atom also forms an inter-molecular N-H?O hydrogen bond with the second amine H atom, generating a zigzag supra-molecular chain along the c axis in the crystal packing. The chains are linked into layers in the bc plane by N-H?Br hydrogen bonds, and these layers are consolidated into a three-dimensional architecture by C-H?? inter-actions.
