چکیده
The title structure, C(9)H(11)N(3)O(2), is a racemate. The chiral centre is situated at the N-C-N C atom of the imidazolidine ring. The inter-planar angle between the mean planes of the pyridine and imidazolidine rings is 89.41 (5)°. The methyl group is in a trans position with respect to the pyridine N atom. In the crystal, the mol-ecules are arranged in zigzag layers parallel to the b axis. The mol-ecules within the layers are inter-connected by strong O-H⋯N and weak N-H⋯O hydrogen bonds; the former take place between OH groups and amine N atoms and the latter between the amine N atom and the carbonyl O atom. In addition, C-H⋯O inter-actions are also present.

In the title complex, [CuBr(2)(C(19)H(15)N(3)O(2))], the metal ion is coordinated by the N,N',O-tridentate 2-hydr-oxy-N'-[phen-yl(2-pyrid-yl)methyl-ene]benzohydrazide ligand and two bromide ions, resulting in a distorted CuN(2)OBr(2) square-based pyramidal coordination geometry with one bromide ion in the apical site. An intra-molecular N-H⋯O hydrogen bond occurs in the ligand. In the crystal, ...

In the title compound, C(18)H(16)N(2)O(3), the dihedral angle between the naphthalene ring system and the pyridyl ring is 18.1 (8)°. The mol-ecules are inter-connected via C-H⋯O and O-H⋯O hydrogen bonds. Inversion-related mol-ecules are linked by O-H⋯O hydrogen bonds into cyclic centrosymmetric R(2) (2)(22) dimers. Intra-molecular N-H⋯O hydrogen bonding produces an S(5) ring motif. The crystal ...
