(1S*,2S*,4R*,5R*)-Cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid.

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 cyclo-hexane ring adopts a chair conformation. Two crystallographycally independent carb-oxy-lic acid groups on adjacent C atoms are in equatorial positions, resulting in a mutually trans conformation. In the crystal, O-H?O hydrogen bonds around an inversion centre and a threefold rotoinversion axis, respectively, form an inversion dimer with an R 2 (2)(8) motif and a trimer with an R 3 (3)(12) motif.
