Structure of Liquid Crystalline 1-Phenyl-3-{4-[4-(4-Octyloxybenzoyloxy) Phenyloxycarbonyl]phenyl}triazene-1-Oxide At Low Temperature

Abstract

The molecular structure of 1-phenyl-3-{4-[4-(4-octyloxybenzoyloxy)- phenyloxycarbonyl]phenyl}triazene-1-oxide, a member of newly developed liquid crystalline homologous series, has been investigated by crystal X-ray crystallography at low temperature (100K). The title compound crystallizes in the triclinic crystal class in the space group P[image omitted] with cell parameters a=5.766(5), b=12.151(10), c=21.751(17), =79.089(13), =88.646(14), =84.278(14), V=1489(2)3 for Z=2. It establishes the N-oxide form of the triazene-1-oxide moiety. The overall molecule is not planar, the dihedral angles between pairs of adjacent benzene rings are 14.00 (10), 52.36 (07), and 50.57 (07). Intramolecular N-HO hydrogen-bonding is present within the triazene-1-oxide moiety of the title compound. The compound forms inversion dimer via an intermolecular N-HO and an intermolecular C-HO links. The dimers are then linked into chains in a parallel fashion by C-HO hydrogen bonds. The crystal packing is further stabilized by C-H interactions.
