A projection of the structure of (I)

on to the bc plane, showing the packing of hydrogen-bonded corrugated layers and directional C—H⋯O interactions that occur between successive layers. Dashed lines indicate hydrogen bonds, N atoms are shaded gray and O atoms are shown as crossed spheres. [Symmetry code: (iv) x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , z.]
