# 4. TEXT


_publ_section_abstract
;
The title complex C~26~H~30~O~7~ contains two 2,3,4 three-substituted
benzylidene units which differ in the orientations of the cyclohexanone ring
system. The crystal structure is stabilized by intermolecular C¡ªH...¦Ð
interactions.
;  

_publ_section_comment
;
The title compound was obtained by the reaction of acetic acid,
tetrahydrofuran, cyclohexanone and 2,3,4-tri-methoxy-benzaldehyde.
Bond lengths are normal and are comparable to the corresponding values
observed in (2E,6E)-2,6-Bis(3,5-di-ter-butyl-4-hydroxy-benzylidene)
cyclohexanone acetic acid solvate(Zhi-Yun Du et al., 2005). No hydrogen
bonds were observed in the complex. The crystal structure
is stabilized by intermolecular C¡ªH...¦Ð interactions.

A mixture of acetic acid saturated by sodium hydroxide (5ml),
dihydrofuran (10mL), cyclohexanone (0.01mol)and
2,3,4-tri-methoxy-benzaldehyde (0.02mol) was stirred at
20-25¡æ for 1h.Later,the reaction mixture was kept in romm temperature
for five days.Yellow crystal appeared.The product was filtered,washed
with ice-cold water,dried and recrystallized from acetone.The yield
90.2%. Elemental analysis, calcd (%) for
C~26~: C 68.71, H 6.65; found(%): C 68.02, H 6.60.
