In the title compound, C(28)H(22)N(4)O(4), the mol-ecule lies on a crystallographic twofold axis. The quinoline ring is essentially planar (give max or rms deviation 0.0186 Å), and the dihedral angle between the quinoline ring and the central benzene ring is 19.1 (4)°. Intra-molecular N-H⋯(N,O) and C-H⋯O hydrogen bonds contribute to the formation of the roughly planar configuration. The crystal...

In the mol-ecule of the title compound, C(25)H(17)N(5)O(2), the pyridyl ring is oriented at dihedral angles of 8.90 (3) and 28.67 (4)° with respect to the two planar quinolyl ring systems. Intra-molecular N-H⋯N hydrogen bonds result in the formation of four planar five-membered rings, two of which are nearly coplanar with the adjacent quinolyl ring systems.

In the title compound, C(18)H(16)N(2)O(2)·H(2)O, the dihedral angle between the quinoline ring system and the benzene ring is 87.19 (8)°. In the crystal, water mol-ecules are linked to acetamide mol-ecules via inter-molecular O-H⋯N and O-H⋯O hydrogen bonds.

The mol-ecular and crystal structures of the title compound, C(23)H(28)Cl(2)N(2)O(2), are very close to those of the bromine-substituted analogue N,N-dicyclo-hexyl-2-(5,7-dibromo-8-quinol-yloxy)acetamide. The two cyclo-hexyl groups adopt normal chair conformation. The amide N and C atoms have a planar configuration. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds and a...
