The structure of chloramphenicol, C11H12Cl2N2O5, an important broad-spectrum antibiotic, was solved by direct methods and refined by Fourier and least-squares to a R of 0.069. The crystals are orthorhombic, space group C2221, with a 7.335(3), b 17.552(8), and c 22.159(6) Å; d.(calcd.) = 1.50 and d.(obsd.) = 1.49 for Z = 8. The side chain exists in the 'alicyclic' form, stabilized by H bonding between the hydroxyl groups. The dichloroacetamido moiety is folded back over the Ph ring
