Quinoline based new Schiff bases were synthesized from 3-Actyl 4-Hydroxy Quinolin-2-(1H)-one and screened their antibacterial antifungal activity. The 4-hydroxy-3-(1-((4-picolin-2-yl)imino)ethyl)quinolin-2-(1H)-one(L1),4-hydroxy-3-(1-((5-picolin-2-yl)imino)ethyl)quinolin-2(1H)-one(L2),4-hydroxy-3-(1-((6-picolin-2-yl)-imino)ethyl)quinolin-2(1H)-one(L3) 4-hydroxy-3-(1-((3-nitro-4-picolin-2-yl)imi...

In the title complex, [Cu(C(15)H(13)NO(4))(C(10)H(8)N(2))], the Schiff base ligand is derived from the condensation of 2-hydr-oxy-1-naphthaldehyde and l-threonine. The Cu(II) atom is five-coordinated by one N atom and two O atoms from the Schiff base ligand and by two N atoms from a 2,2'-bipyridine ligand in a distorted square-pyramidal geometry. In the crystal structure, the combination of int...

The title compound, C(31)H(20)N(2)O(5)·C(2)H(3)N, was synthesized by the reaction of fluorescein hydrazide and excess 2-hydr-oxy-1-naphthaldehyde in acetonitrile. The spirolactam ring is planar and is nearly at right angles to the two benzene rings of the xanthene system. The dihedral angle between the two benzene rings of the xanthene system is 9.92 (4)°. In the crystal structure, the mol-ecul...

The title compound, C(19)H(15)ClN(2)O(2), was prepared by the reaction of 2-meth-oxy-1-naphthaldehyde with 3-chloro-benzohydrazide in methanol. The dihedral angle between the benzene ring and the naphthyl ring system is 69.0 (3)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis. The crystal packing exhibits π-π inter-actions, as indicated by...

The title compound, C(18)H(13)BrN(2)O(2), was synthesized by the reaction of 2-hydr-oxy-1-naphthaldehyde with an equimolar quantity of 3-bromo-benzohydrazide in methanol. The dihedral angle between the benzene ring and the naphthyl ring system is 18.3 (2)°. An intra-molecular O-H⋯N hydrogen bond is observed between the phenolate O and imine N atoms. In the crystal structure, mol-ecules are link...
