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. ; _publ_section_acknowledgements ; We acknowledge financial support by the Science and Technology Program Foundation of Guang Zhou(2006B13501002). ; _publ_section_related_literature ; ; _publ_section_references ; Youssef, K.
