Abstract :
In the title compound, C14H18O8, (I), the methoxycarbonyl [–C( O)OCH3] and
the acetic acid [–CH2C( O)OH] groups are inclined to the benzene ring by
79.24 (11) and 76.71 (13), respectively, and are normal to each other with a
dihedral angle of 90.00 (13). In the crystal, molecules are linked by a pair of
O—HO hydrogen bonds forming the familiar acetic acid inversion dimer. The
dimers are linked by two C—HO hydrogen bonds and an offset –
interaction [intercentroid distance = 3.6405 (14) A˚ ], forming layers lying parallel
to the (101) plane. The layers are linked by a third C—HO hydrogen bond
and a C—H interaction to form a supramolecular framework.
