(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.

By contrast, the caffeine mol-ecule is planar (r.m.s. deviation = 0.040?Å).

These stack via ?-? inter-actions between the benzene and imidazole rings [inter-centroid distance = 3.4503?(10)?Å].
