摘要：

In the crystal structure of the title compound, C19H24O8, the molecules adopt a conformation in which the bulky 2,6-dimethoxyphenoxy and 4-hydroxy-3,5-dimethoxyphenyl groups are almost as far apart as possible. The C( aryl) center dot center dot center dot C(aryl) distance is 4.8766 (19) angstrom, which is close to the calculated maximum value (4.92 angstrom). The C(aryl) - C - C - O(aryloxy) torsion angle is 173.76 (11) degrees and the C(benzylic) - C - O - C(aryl) torsion angle is 149.09 (11)degrees. The conformation is compared with those of related lignin model compounds. The hydrogen-bonding pattern is discussed in terms of graph-set theory.
