Abstract
In the title mol-ecule, C14H13NO2, the dihedral angle between the planes of the benzene rings is 65.18 (4)°. The central amide group has about the same degree of twist with respect to both ring planes, as indicated by the dihedral angles of 34.70 (8) and 30.62 (8)° between its plane and that of the phenyl and 4-meth-oxy-benzene rings, respectively. The C atom of the meth-oxy group is close to being coplanar with its attached ring [deviation = -0.112 (2) Å]. In the crystal, mol-ecules are linked by inter-amide N-H⋯O hydrogen bonds, which generate C(4) chains propagating in the [100] direction. Adajcent mol-ecules in the chain are related by translational symmetry.Entities:

| 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. |
