The stilbazole is disordered and modelled in two positions, differing by
rotation about the 1,4 axis. These were found to have equal occupancy.
For each stilbazole position there was further disorder of the central
double bond. In each case this was modelled in two positions with
refined occupancies of 0.311:0.185(7) and 0.435:0.065(6). The various
central C(12)=C(13) bonds were restrained to have equal lengths and
the ADP of the 4 C12 atoms were constrained to be identical as were
the 4 C13. For the butyl chain, the pairs of C-O and C-C bonds were
restrained to have equal lengths.
