3-(E)-(3-tert-Butyl-1-phenyl-1H-pyrazol-5-yl)imino­methylquinolin-2(1H)-one: chains built by π-stacking of hydrogen-bonded R 2 2(8) dimers

摘要

In the title compound, C23H22N4O, there is evidence for some bond fixation in the aryl component of the quinolinone unit. Pairs of mol­ecules related by inversion are linked into R 2 ²(8) dimers by almost linear N—H⋯O hydrogen bonds, and dimers related by inversion are linked into chains by a single aromatic π–π stacking inter­action.
