The Kinetic and Thermal Degradation Studies of N-(4-Acetyl-phenyl)-acetimidic Acid Pyridine-3-yl ester Metal(II) Complexes
Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. Th...
متن کاملSynthesis and Characterization of Some Lanthanide(III) Chloro Complexes Derived from 4[N-(4’-Hydroxy-3’-Methoxybenzalidene) Amino] Antipyrine Semicarbazone and 4[N-(3’,4’,5’-Trimethoxybenzalidene) Amino]Antipyrine Semicarbazone
Lanthanide(III) chloro complexes of 4[N-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (HMBAAPS) (I) and 4[N-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (TMBAAPS) (II) with the general composition LnCl3.2L (Ln = La, Pr, Nd, Sm, Gd, Tb, Dy or Ho; L = HMBAAPS or TMBAAPS) are reported. All the complexes were synthesized in ethanolic medium and refluxed the ...
متن کاملrac-4-[4-Cyano-2-(hydroxymethyl)phenyl]-4-(4-fluorophenyl)-4-hydroxy-N,N-dimethylbutanaminium hemifumarate
In the title salt, C(20)H(24)FN(2)O(2) (+)·0.5C(4)H(2)O(4) (2-), the fumarate anion is located on an inversion centre. In the cation, the two benzene rings are nearly perpendicular to each other, making a dihedral angle of 87.41 (10)°. The cation is linked to the anion by a bifurcated N-H⋯O hydrogen bond. Classical O-H⋯O and weak C-H⋯F hydrogen bonding is also present in the crystal structure. ...
متن کامل4-Ethoxy-N-(4-ethoxyphenyl)-N-(4-nitrophenyl)aniline
In the title mol-ecule, C22H22N2O4, the eth-oxy-phenyl rings are oriented at dihedral angles of 69.31 (13) and 75.90 (13)° to the nitro-phenyl ring and are twisted to each other, making a dihedral angle of 78.55 (13)°. In the crystal, weak C-H⋯O hydrogen bonds and C-H⋯π inter-action link the mol-ecules into a three-dimensional supra-molecular architecture.
متن کاملN 4,N 4′-Bis(4-methoxybenzylidene)-3,3′-dimethylbenzidine
The mol-ecule of the title compund, C(30)H(28)N(2)O(2), a Schiff base synthesised via a condensation reaction between 4-meth-oxy-benzaldehyde and 3,3'-dimethyl-benzidine, a crystallographic twofold rotation axis passes through the mid-point of the C-C bond of the biphenyl unit. Thus, the asymmetric unit comprises one half-mol-ecule. In the biphenyl unit, the aromatic rings are twisted by 13.49 ...
