Abstract The compound with the general formula C n H 2 n +1 –COO–C 6 H 4 –C 6 H 4 –OOC–C n H 2 n +1 , n = 14 (SYM‐ 14) crystallizes in the triclinic space group P 1 , with a = 5.431(5), b = 9.346(8), c = 39.172(51) Å, α = 92.60(15), β = 90.65(15), γ = 100.364(8)°. The crystal structure was solved by direct methods. Least‐squares refinement leads to a final R value of 0.092 for 1575 observed reflections, with I > 2σs( I ). The packing arrangement follows the same building principles found recently for the first three members of the well known homologous series of liquid crystalline terephthalylidine‐anilines (TBAA‐n).
