In order to clarify relationships between the mesophase behaviour and
crystal structures, the X-ray structure determinations of the title co
mpounds, ethyl 4-(4-n-octyloxybenzoyloxy)benzylidene]aminobezoate C31H
35NO5, and butyl 4-n-octyloxybenzoyloxy)-benzylidene]aminobenzoate, C3
3H39NO5, have been performed. The compounds have different phase seque
nces, i.e. crystal-smectic A-nematic-isotropic and crystal-smectic C-s
mectic A-nematic-isotropic for the ethyl and butyl compounds, respecti
vely.
