6,6-dihydropenicillanate S,S-dioxide 5 was prepared and determined by X-ray crystallography. Single-crystal X-ray diffraction analysis reveals that the molecular structure of compound 5b is enantiomerically pure. The crystal belongs to orthorhombic, space group P2(1)2(1)2(1), with unit cell parameters a = 6.5366 angstrom, b = 10.7649(9) angstrom, c = 15.5879(13) angstrom, V = 1096.86(16) angstrom(3), D-x = 1.491 g cm(-3), Z = 4, T = 296(2)K, F(000) = 520, R-1 = 0.0401, and wR(2) = 0.1200. Absolute structure parameter is 0.02(10).
