The crystal and molecular structure of 1-(p-iodobenzenesulfonyl)-1-azaspiro[2,5] octane

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 Å. 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.
