چکیده
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.

The title compound, C(27)H(39)N(3)O(2)·H(2)O, is a chiral pyridine-2,6-dicarboxamide derivative including cis-myrtanyl groups as amine substituents. The pyridine-2,6-dicarboxamide core approximates C(2) point symmetry and a solvent water mol-ecule lies on the pseudo-twofold axis. The water mol-ecule serves both as acceptor and donor for efficient hydrogen bonds involving N-H and C=O functional ...

The mol-ecule of the title compound, C19H13Br2N3O2, lies about a twofold rotation axis. The benzene ring makes dihedral angles of 8.9 (2) and 16.4 (2)° with the central pyridine ring and the second benzene ring, respectively. An intra-molecular N-H⋯N contact occurs. In the crystal, mol-ecules are connected by pairs of N-H⋯O hydrogen bonds into chains along the c axis.
