Crystal-structure and Spectroscopic Study of 2-[(2,6-dichlorophenyl)amino]phenylacetoxyacetic Acid (aceclofenac)

The crystal structure of the title compound has been determined. The crystals are monoclinic: P2(1)/n (NO. 14), a = 12.279(7), b = 8.223(1), c = 15.504(7) angstrom, beta = 96.16(2)-degrees, V(c) = 1556(2) angstrom3, Z = 4, D(x) = 1.511 g cm-3, lambda = (Mo Kalpha) = 0.71069 angstrom. The structure was solved by direct methods and refined with 1970 reflections to a final R value of 0.057. Analytical, mass, spectral, and physicochemical data are also reported
