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 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 کامل4-Hydroxy-4,6a,6b,9,9,12a,14b-heptamethylperhydropicen-3-one hemihydrate isolated from Adiantum incisum
The title compound, C(29)H(48)O(2)·0.5H(2)O, is a triterpenoid isolated from the stems and rhizomes of Adiantum incisum. The basic skeleton of the mol-ecule contains five six-membered rings, all adopting chair conformations, bearing a total of seven methyl, one hydroxyl and a keto group. There are two mol-ecules of the triterpene and one water molecule of crystallization in the asymmetric unit....
متن کامل3-Hydroxy-4-methoxybenzaldehyde thiosemicarbazone hemihydrate
The asymmetric unit of the title compound, C(9)H(11)N(3)O(2)S·0.5H(2)O, comprises two crystallograpically independent thio-semicarbazone mol-ecules (A and B) and a water mol-ecule of crystallization. In each of the thio-semicarbazone mol-ecules, intra-molecular O-H⋯O and N-H⋯N hydrogen bonds form five-membered rings, producing S(5) ring motifs. Inter-molecular O-H⋯S and N-H⋯O inter-actions betw...
متن کاملN-(3-Chlorophenyl)-4-methylbenzamide hemihydrate
In the title compound, C(14)H(12)ClNO·0.5H(2)O, the water mol-ecule is located on a twofold axis of symmetry. The meta-Cl atom in the aniline ring is positioned anti to the N-H bond. The two benzene rings make a dihedral angle of 40.40 (11)°. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, which link the mol-ecules into chains along the a axis.
