Abstract
(E)-3-(4-Iodophenyl)propenoic acid, C 9 H 7 IO 2 , M r =274.05, monoclinic, P2 1 /n, a=4.118 (2), b=6.274 (4), c=34.672 (2) A, β=90.32 o , V=895.7 (9) A 3 , Z=4, D x =2.03 Mg m -3 , λ(Mo Kα)=0.71069 A, μ=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
