چکیده
In the title compound, C(20)H(18)N(4)O(4), conformation along the bond sequence linking the benzene and quinoline rings, which have a mean inter-planar dihedral angle of 2.7 (5)°, is trans-(+)gauche-trans-trans-(-)gauche-trans-trans. In the crystal structure, a pair of inter-molecular N-H⋯O hydrogen bonds links the mol-ecules into centrosymmetric cyclic R(2) (2)(8) dimers, which are aggregated via π-π inter-actions into parallel sheets [quinoline-benzene ring centroid separation = 3.6173 (16)-3.6511 (16) Å]. The sheets are further connected through weak C-H⋯O inter-actions, giving a supra-molecular two-dimensional network.
