4'-[2-(2-Ethoxy-ethoxy)eth-oxy]-bi-phenyl-4-carboxylic acid: Correlation between its crystalline and smectic phases
The crystal structure of the dimeric title compound, C19H 22O5H, is dominated by a head-to-head hydrogen-bonding inter-action between centrosymmetrically related carboxyl groups in each monomer. The result is a dimeric axis of unusual length (ca 34 Å), but still shorter than what could be expected f...
