In the title compound, C(14)H(13)Cl(2)NO(2)S, the C-SO(2)-NH-C torsion angle is -71.4 (4)°. The sulfonyl and aniline benzene rings are tilted relative to one another by 44.6 (1)°. The crystal structure features inversion-related dimers linked by pairs of N-H⋯O hydrogen bonds.

In the title compound, C(13)H(12)ClNO(2)S, the conformation of the N-H bond is anti to the 3-chloro group in the aniline benzene ring. The dihedral angle between the two benzene rings is 73.7 (1)°. The crystal structure features inversion-related dimers linked by pairs of N-H⋯O hydrogen bonds.

In the title mol-ecule, C(17)H(12)INO, the dihedral angle between the naphthaldeyde plane and the 3-iodo-aniline plane is20.07 (13)°. It exists in the solid state as an enol-imine tautomer with a strong intra-molecular O-H⋯N hydrogen bond.

Identification and relative quantification of hundreds to thousands of proteins within complex biological samples have become realistic with the emergence of stable isotope labeling in combination with high throughput mass spectrometry. However, all current chemical approaches target a single amino acid functionality (most often lysine or cysteine) despite the fact that addressing two or more a...

The title compound, C(13)H(9)Cl(2)N, has an intra-molecular C-H⋯O close contact, and presents the NH group syn to the meta-chloro group in the aniline ring and trans to the C=O group. The crystal packing is formed by infinite chains of N-H⋯O hydrogen bonds along the c axis. Cl⋯Cl [3.474 (1) Å] contacts link chains. The crystal used for data collection was a twin, the domains related by the twin...

Copper(II) complexes of the ligand 1,n-bis[bis(2-pyridylmethyl)amino]benzene with n = 2-4 (1,n-tpbd) and its mononuclear derivative bis(2-pyridylmethyl)aniline (phbpa) were synthesized and structurally characterized. Magnetic measurements and DFT calculations were performed on [CuCl2(phbpa)], [Cu2Cl4(1,3-tpbd)], [(Cu2Cl2(ClO4)(1,3-tpbd))Cl(Cu2Cl2(OH2)(1,3-tpbd))](ClO4)2, and [Cu2(OH2)2(S2O6)(1,...

In the title compound, C(44)H(48)N(6), the essentially planar mol-ecule [maximum deviation from the mean plane of the π system of 0.271 (3) Å] is located on a crystallographic centre of inversion. The almost planar (angle sums at N atoms = 357.6 and 357.1°) dimethyl-amino groups and short C-N bonds of the aniline groups [both 1.379 (4) Å] indicate strong electronic coupling between these groups...

The title compound, C17H17NO3, prepared by the condensation reaction of 2-(1,3-dioxan-2-yl)aniline and salicyl-aldehyde, has an E conformation about the C=N bond. The six-membered O-heterocycle adopts a chair conformation, with the bond to the aromatic ring located at its equatorial position. The dihedral angle between the aromatic rings is 36.54 (9)°. There is an intra-molecular N-H⋯O hydrogen...

The title compound, C(14)H(5)F(6)NO(3), was synthesized by condensation of tetra-fluoro-phthalic anhydride and 2,4-difluoro-aniline. It was then recrystallized from hexane to give a nonmerohedral twin with two crystallographically unique mol-ecules in the asymmetric unit. The refined twin fraction is 0.460 (3). Torsional differences between the aryl rings and the central amide group account for...
