Beschreibungen/Notizen

• In the title compounds, C H N OS (I) and C H N O S (II), the dihedral angle between the pyrimidine and benzene rings is 58.64 (8)° in (I) and 78.33 (9)° in (II). In both compounds, there is an intra-molecular C-H⋯O hydrogen bond, and in (II) there is also an intra-molecular N-H⋯N hydrogen bond present. In the crystals of both compounds, a pair of N-H⋯N hydrogen bonds links the individual mol-ecules to form inversion dimers with (8) ring motifs. In (I), the dimers are linked by N-H⋯O and C-H⋯O hydrogen bonds, enclosing (14), (11) and (7) ring motifs, forming layers parallel to the (100) plane. There is also an N-H⋯π inter-action present within the layer. In (II), the inversion dimers are linked by N-H⋯O hydrogen bonds enclosing an (18) ring motif. The presence of N-H⋯O and C-H⋯O hydrogen bonds generate an (6) ring motif. The combination of these various hydrogen bonds results in the formation of layers parallel to the (1-11) plane.
