Ethyl 4,4''-difluoro-5'-meth-oxy-1,1':3',1''-terphenyl-4'-carboxyl-ate.

ABSTRACT: In the title compound, C(22)H(18)F(2)O(3), the two fluoro-substituted rings form dihedral angles of 25.89?(15) and 55.00?(12)° with the central benzene ring. The eth-oxy group in the mol-ecule is disordered over two positions with a site-occupancy ratio of 0.662?(7):0.338?(7). In the crystal, mol-ecules are linked by C-H?O hydrogen bonds into chains along the a axis. The crystal packing is further stabilized by C-H?? and ?-? inter-actions, with centroid-centroid distances of 3.8605?(15)?Å.

Dimethyl 3,3'-di-meth-oxy-biphenyl-4,4'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the biphenyl moiety is twisted with a dihedral angle of 29.11 (10)°. The carbometh-oxy groups form C-C-C-O torsion angles of -18.3 (3) and -27.7 (3)° with the attached rings, as a result of steric hindrances from the nearby meth-oxy groups. In the absence of stacking inter-actions and with no H⋯O contacts shorter than 2.7 Å, the packing is dominated by weaker van der Waals inter-actions.
