N-[4-Chloro-3-(trifluoro-meth-yl)phen-yl]-2,2-dimethyl-propanamide.

ABSTRACT: In the title compound, C(12)H(13)ClF(3)NO, the C-C-N-C torsion angle between the benzene ring and the pivaloyl group is -33.9 (5)°. In the crystal, molecules are linked via N-H⋯O hydrogen bonds to form chains running parallel to the c axis. Weak van der Waals inter-actions are also observed.

3-Chloro-N-(4-meth-oxy-phen-yl)propanamide.

Project description:The title compound, C(10)H(12)ClNO(2), is a halogenated derivative of a secondary amide bearing an aromatic substituent. The C(=O)-N(H)-C(ar)-C(ar) torsion angle of -33.70?(18)° rules out the presence of resonance spanning the amide as well as the aromatic system. In the crystal, classical N-H?O hydrogen bonds, as well as C-H?O contacts connect the mol-ecules into chains propagating along the a axis.

N-Ethyl-2,2-dimethyl-N-(3-methyl-phen-yl)propanamide.

Project description:In the title compound, C14H21NO, the conformation across the N-C(O) bond is syn-periplanar, the C-N-C-C torsion being -5.9?(5)°.

C-H?? inter-actions link the mol-ecules along the c-axis direction.

4'-[2-(Trifluoro-meth-yl)phen-yl]-2,2':6',2''-terpyridine.

Project description:The title compound, C(22)H(14)F(3)N(3), is a versatile tridentate N-donor ligand consisting of a terpyridyl (terpy) molecule substituted in the 4'-position by a phenyl group, itself substituted in an ortho-position by a bulky trifluoro-methyl group. The phenyl ring is twisted as a result of steric inter-actions involving the bulky trifluoro-methyl substituent. This is reflected in the dihedral angle between the mean plane through the C atoms of the phenyl ring and the terpyridyl unit being 69.2?(1)°. The crystal structure contains no short van der Waals contacts. However, the terpy units stack in a head-to-tail orientation perpendicular to the c axis. The structure is is loosely stabilized by ?-? inter-actions between the terminal pyridine rings of adjacent mol-ecules along the stack. The perpendicular distance between the mean planes through the terpy moieties of adjacent mol-ecules is 3.4?(1)?Å.
