Diethyl 4,4'-(3,6-dioxaoctane-1,8-diyl-dioxy)dibenzoate.


ABSTRACT: The title compound, C(24)H(30)O(8), was obtained by reaction of ethyl 4-hy-droxy-benzoate with 1,2-dichloro-ethane. The mol-ecule occupies a crystallographic inversion center, with its central ethyl-ene bridge in an anti conformation. The other ethyl-ene bridge has a gauche conformation, with the corresponding O-C-C-O torsion angle being 74.2?(1)°. The benzene rings are almost coplanar with the adjacent eth-oxy-carbonyl groups, with an r.m.s. deviation of 0.078?Å.
