2-Hydroxy-3-methoxybenzaldehyde 2,4-dinitrophenylhydrazone pyridine monosolvate
The Schiff base molecule of the title compound, C(14)H(12)N(4)O(6)·C(5)H(5)N, was obtained from the condensation reaction of 2-hy-droxy-3-meth-oxy-benzaldehyde and 2,4-dinitro-phenyl-hydrazine. The C=N bond of the Schiff base has a trans arrangement and the dihedral angle between the two benzene rings is 3.49 (10)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, ...
متن کاملDirect Spectrophotometric determination of Aluminum (III) using 5-Bromo-2-hydroxy-3-methoxybenzaldehyde-P- hydroxybenzoic hydrazone
Highly sensitive and selective direct spectrophotometric method is proposed for the determination of aluminium in various real samples. 5-Bromo-2-hydroxy-3-methoxybenzaldehyde-phydroxybenzoic hydrazone reacts with Al(III) forming yellow coloured soluble complex in aqueous dimethyl formamide which has a λmax at 390 nm in the pH range 3.0-7.0. The system obeyed Beer’s law in the range 0.053 – 0.7...
متن کاملDirect Spectrophotometric Determination of Ni (II) Using 5- Bromo-2- hydroxyl -3-methoxybenzaldehyde-4-hydroxy benzoichydrazone
: A rapid, simple,sensitive and selective direct spectrophotometric method has been developed for the determination of nickel(II) in various real samples. 5-Bromo-2-hydroxy-3-methoxy benzaldehyde-p-hydroxybenzoic hydrazone reacts with Ni(II) forming green coloured soluble complex [ ( Ni(II)-5-BHMBHBH] in basic buffer solution. The maximum absorbance was observed in the pH range 5.5-7.5 and Ni(I...
متن کاملGallic acid pyridine monosolvate
IN THE TITLE COMPOUND (SYSTENATIC NAME: 3,4,5-trihy-droxy-benzoic acid pyridine monosolvate), C(5)H(5)N·C(7)H(6)O(5), the gallic acid mol-ecule is essentially planar (r.m.s deviation = 0.0766 Å for non-H atoms) and is linked to the pyridine mol-ecule by an O-H⋯N hydrogen bond. An intra-molecular O-H⋯O hydrogen bond occurs in the gallic acid mol-ecule. The gallic acid and pyridine mean planes ma...
متن کاملTizoxanide pyridine monosolvate
IN THE TITLE COMPOUND [SYSTEMATIC NAME: 2-hy-droxy-N-(5-nitro-1,3-thia-zol-2-yl)benzamide pyridine monosolvate], C(10)H(7)N(3)O(4)S·C(5)H(5)N, the dihedral angle between the pyridine and benzamide rings is 80.55 (7)°. An intamolecular O-H⋯N hydrogen bond occurs in the tizoxanide. In the crystal, the components are linked by an O-H⋯N hydrogen bond, forming a zigzag chain along the c axis. Aromat...
