%X The potential porphyrin precursor ethyl 5-p-tolylsulfonyl-2,4,5,6-tetrahydropyrrolo&#91;3,4-c&#93;pyrrole-1- carboxylate has been synthesized and its crystal structure determined by X-ray methods, giving a refinement residual R 0&#183;038 for 5130 observed reflections. Crystals are triclinic, space group P 1, with Z = 4 in a cell of dimensions a 10&#183;5030(6), b 11&#183;2843(8), c 15&#183;236(1) &#197;, &#945; 109&#183;419(6), &#946; 97 &#183; 697(6), &#947; 95 &#183; 651(6)&#176;. The two molecules in the crystallographic repeating unit are pseudo-mirror-related, and the heterocyclic system is almost planar in both molecules.
