Experimental and theoretical characterization of a new Schiff-base ligand
Here, new N,N′-dipyridoxyl(4,4''-diaminodiphenylether) Schiff-base ligand has been synthesized and characterized by IR, 1H NMR and mass spectrometry. Also, geometry optimization and theoretical assignment of IR spectrum of the ligand have been computed by employing density functional theory (DFT) method. Two pyridine rings and benzene rings in the bridge region are not in the same plane. The ca...
متن کامل(2S)-1,1-Dichloro-2-(2-chlorophenyl)-2-(4-chlorophenyl)ethane
The title compound, C(14)H(10)Cl(4), is easily crystallized while the other enanti-omorph only forms an oil upon crystallization attempts. The title compound has a considerably higher density, ρ ≃ 1.562 Mg m(-3) compared to the racemic substance, ρ ≃ 1.514 Mg m(-3). This is supported by the fact there are two inter-molecular halogen-halogen contacts in the title compound compared with only one ...
متن کامل1-Bromo-2-(4-methoxyphenoxy)ethane
In the crystal structure of the title compound, C(9)H(11)BrO(2), mol-ecules are stacked parallel to the b-axis direction, forming double layers in which the molecules are arranged head-to-head, with the bromo-methyl groups pointing towards each other.
متن کامل4-Aminobenzoic acid–1,2-bis(4-pyridyl)ethane (2/1)
In the title compound, C(12)H(12)N(2)·2C(7)H(7)NO(2), the 4-amino-benzoic acid mol-ecules are linked by O-H⋯N hydrogen bonds to 1,2-bis-(4-pyrid-yl)ethane, forming linear hydrogen bonded chains parallel to [21]. The structure exhibits a hydrogen-bonding network involving COOH⋯N(pyrid-yl) and amine and carb-oxy-lic N-H⋯ O inter-actions. In addition, π-π stacking inter-actions [centroid-centroid ...
متن کاملN,N′-Bis[1-(thiophen-2-yl)ethylidene]ethane-1,2-diamine
Mol-ecules of the title compound, C(14)H(16)N(2)S(2), have a centre of inversion in the middle of the -CH(2)-CH(2)- bond; the (C(4)H(3)S)(CH(3))C=N-CH(2)- moiety is almost planar (r.m.s. deviation for non-H atoms 0.027 Å).
