In the title compound, C21H22ClNO4 [systematic name: (E)-3-(4-chloro­phen­yl)-3-(3,4-di­meth­oxy­phen­yl)-1-(morpholin-4-yl)prop-2-en-1-one], which is the morpholine fungicide dimethomorph, the dihedral angles between the mean planes of the central chloro­phenyl and the terminal benzene and morpholine (r.m.s. deviation = 0.2233 Å) rings are 71.74 (6) and 63.65 (7)°, respectively. In the crystal, molecules are linked via C—H⋯O hydrogen bonds and weak Cl⋯π interactions [3.8539 (11) Å], forming a three-dimensional structure.

Comment top

Dimethomorph [systematic name: (E)-3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-(morpholin-4-yl)prop-2-en-1-one] is a morpholine fungicide that has been mainly applied on grapevines, apples, ginsengs, tomatoes, potatoes, cucumbers, Chinese cabbage and other crops. (Xu et al., 2015). The dihedral angles between the planes of the central chlorophenyl and the terminal benzene and mean plane [r.m.s. deviation = 0.2233] of morpholine rings are 71.74 (6) and 63.65 (7)°, respectively. All bond lengths and bond angles are normal and comparable to those observed in similar crystal structures (Chai & Liu, 2011; Lu & Shi, 2011).

In the crystal structure (Fig. 2), C—H···O hydrogen bonds (Table 1) and weak intermolecular C11—Cl1···Cg1iv (Cg1 is the centroid of the C8—C13 ring) interaction with a chlorophenyl ring are present, resulting in a three-dimensional network [for symmetry code: (iv), -x, -y + 1, -z + 1].

Experimental top

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH3OH gave single crystals suitable for X-ray analysis.

Refinement top

All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.98 Å, Uiso = 1.5Ueq(C) for methyl group, d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for CH2 group, d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for Csp2—H and aromatic C—H.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
