Abstract
The structure of 1-(p-iodobenzenesulfonyl)-1-azaspiro[2.5]octane was determined by a single-crystal x-ray diffraction study. The compound crystallizes in the orthorhombic space group P21 21 21 with cell dimensions: a = 11.655, b = 11.825, c = 11.068 ± 0.002 A. The aziridine ring is spiro-fused to the cyclohexane ring with the nitrogen atom occupying the equatorial position. The cyclohexane ring is in an undistorted chair conformation and forms a dihedral angle of 97.1° with the aziridine ring. The structure was refined to a final value of R = 0.074 for the 590 independent reflections.
