Crystal structure of pencycuron.

In the title compound [systematic name: 1-(4-chloro-benz-yl)-1-cyclo-pentyl-3-phenyl-urea], C19H21ClN2O, which is a urea fungicide, the cyclo-pentyl ring adopts an envelope conformation, with one of the methyl-ene C atoms adjacent to the C atom bonding to the N atom as the flap. The dihedral angles between the mean planes of the central cyclo-pentyl ring (all atoms) and the chloro-benzyl and phenyl rings are 77.96 (6) and 57.77 (7)°, respectively. In the crystal, N-H⋯O hydrogen bonds link adjacent mol-ecules, forming C(4) chains propagating along the b-axis direction. The chains are linked by weak π-π inter-actions between the chloro-benzene rings [centroid-centroid separation = 3.9942 (9) Å], resulting in two-dimensional networks extending parellel to the (110) plane.

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.
