Abstract: The title compound, C10H12O8, a prospective raw material for colourless polyimides which are applied to electronic and microelectronic devices, lies about an inversion centre and the cyclohexane ring adopts a chair conformation. Two crystallographycally independent carboxylic acid groups on adjacent C atoms are in equatorial positions, resulting in a mutually trans conformation. In the crystal, O-HO hydrogen bonds around an inversion centre and a threefold rotoinversion axis, respectively, form an inversion dimer with an R22(8) motif and a trimer with an R33(12) motif.
