摘要：

(E)-3-(4-Iodophenyl)propenoic acid, C9H7IO2, M(r) = 274.05, monoclinic, P2(1)/n, a = 4.118 (2), b = 6.274 (4), c = 34.672 (2) angstrom, beta = 90.320, V = 895.7 (9) angstrom3, Z = 4, D(x) = 2.03 Mg m-3, lambda(Mo Kalpha) = 0.71069 angstrom, mu = 34.90 cm-1, F(000) = 520, T = 153 K, R = 0.037, wR = 0.043 for 1098 reflections. The crystal structure is characterized by O-H...O, C-H...O and I...I interactions and resembles the packing of 4-iodobenzoic acid and 4-chlorocinnamic acid. The Cambridge Structural Database has been used to study the disorder of the carboxyl group in 47 benzoic acids and 25 cinnamic acids.
