ZEITSCHRIFT FUR KRISTALLOGRAPHIE（1992）
Abstract
The title compound C11H8O2S (1) crystallizes in space group C2/c: a = 11.468(4) angstrom, b = 8.767(1) angstrom, c = 19.249(6) angstrom, beta = 107.20(2)-degrees; V = 1848.6(1.4) angstrom3; Z = 8, D(x) = 1466 kg M-3; Cu Kalpha = 1.542 angstrom, mu = 27 cm-1; F(000) = 848; T = 293(1) K; Conventional R = 0.10 = R(w) for 1594 unique reflections. (I) is almost flat and exhibits no pharmacological activity, whereas is non-planar phenyl derivative (II) has a strong antalgic action.
