A Schiff base was prepared from the interaction of ethanolic solutions of 2-hydroxy-1– naphthaldehyde and butylenediamine. The complexes were synthesized by refluxing the mixture of ethanolic solutions of the Schiff base and respective metal (II) chloride. Their solubility, melting point/decomposition temperature, molar conductance, elemental analysis and IR were carried out. The melting point ...

The title compound, C(18)H(13)ClN(2)O(2), was prepared by the reaction of 2-hy-droxy-1-naphthaldehyde with 3-chloro-benzohydrazide in methanol. An intra-molecular O-H⋯N hydrogen bond influences the mol-ecular conformation; the benzene ring and naphthyl ring system form a dihedral angle of 17.1 (3)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains propagated ...

The title Schiff base compound, C(16)H(14)N(2)O(2), has been synthesized by the reaction of 5-amino-3,4-dimethyl-isoxazole and 2-hydr-oxy-1-naphthaldehyde. The dihedral angle between the isoxazole ring and the napthyl ring system is 3.29 (7)°. The mol-ecule adopts an E configuration about the central C=N double bond. Intra-molecular O-H⋯N hydrogen bonding generates an S(6) ring motif. In the cr...

The title Schiff base compound, C(19)H(18)N(2)O, was prepared by the reaction of equimolar quanti-ties of 2-hydr-oxy-1-naphthaldehyde with N-phenyl-ethane-1,2-diamine in a methanol solution. The mol-ecule adopts a zwitterionic conformation with the naphthyl OH group deprotonated and the imine N atom protonated. An intra-molecular N-H⋯O hydrogen bond forms between them. The dihedral angle betwee...

The title compound, C(18)H(15)N(3)O(2), was prepared by the reaction of 2-methoxy-naphthaldehyde with nicotinic acid hydrazide in methanol. The dihedral angle between the naphthalene ring system and the pyridine ring is 9.2 (3)°. An intra-molecular C-H⋯N hydrogen bond is observed. In the crystal structure, mol-ecules are linked into chains running along the c axis by inter-molecular N-H⋯O hydro...
