In the asymmetric unit of the title hydrazone compound, C(15)H(10)Br(2)N(2)O(4), there are two independent mol-ecules. In each mol-ecule, the five-membered ring adopts a flattened envelope conformation; the flap atoms are displaced by 0.114 (2) and 0.219 (2) Å from the planes of the other four atoms. In one mol-ecule the dihedral angle between the two benzene rings is 22.8 (2)°, while in the ot...
In the title Schiff base compound, C(13)H(9)Br(2)N(3)O(2), there is an intra-molecular O-H⋯N hydrogen bond involving the hydroxyl substituent and the adjacent hydrazine N atom. The mol-ecule is almost planar, the dihedral angle between the benzene ring and the pyridine ring being 5.7 (2)°. In the crystal structure, symmetry-related mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains ...
A novel polyfunctional dipodal ligand, L = N,N'-bis[2-[(2-hydroxy-1-naphthyl)methyleneamino]ethyl]propanediamide (DOTA2HNAP) was developed and characterized through elemental and spectral analyses. The complexation behavior of the ligand was investigated with Co2+, Cu2+, and Zn2+ metal ions by potentiometric and spectrophotometric methods in H2O-D...
