4-(Oct-yloxy)phenyl 2-oxo-2H-chromene-3-carboxyl-ate.

ABSTRACT: In the title compound, C(24)H(26)O(5), the 2H-chromene ring system is essentially planar, with a maximum deviation of 0.029?(2)?Å from the best-fit mean plane incorporating both rings. The dihedral angle between the 2H-chromene ring system and the benzene ring is 21.00?(1)°. In the crystal, pairs of C-H?O hydrogen bonds generate an R(2) (2)(8) ring pattern. These contacts are bolstered by weaker bifurcated C-H?O hydrogen bonds.

Project description:The title compound, C31H27F3O7, is a liquid crystal and exhibits enanti-otropic SmA and nematic phase transitions. In the crystal, the the 2H-chromene ring system makes dihedral angles of 54.46 (17) and 7.79 (16)°, respectively, with the central benzene ring and 4-(hept-yloxy)benzene ring. The three F atoms of the -CF3 group are disordered over two sets of sites, with an occupancy ratio of 0.62 (3):0.38 (3). The crystal structre features two pairs of C-H⋯O hydrogen bonds, which form inversion dimers and generate R 2 (2)(10) and R 2 (2)(30) ring patterns. C-H⋯O inter-actions along [100] and C-H⋯π inter-actions futher consolidate the packing, leading to a three-dimensional network.
