对碘苯氧乙酸[IC6H4OCH2COOH]系单斜晶系,空间群P2_1/C,a=13.86,b=5.28,c=12.57A,β=100°,V=906A3,z=4,D_观=2.058克/立方厘米,D_计=2.041克/立方厘米。它和其他许多取代苯甲酸一样,也是通过氢键形成具有对称中心的双缔合分子。氢键长2.62A,苯环与双聚羧基平面相交约15°。苯环平均键长1.38A,平均键角119.9°。苯环厚度3.7 A左右。最短I—I原子间距离为2.91A。
P-Iodophenoxyacetic acid [IC6H4OCH2COOH] is a monoclinic with space group P2_1 / C, a = 13.86, b = 5.28, c = 12.57A, β = 100 °, V = 906A3, z = 4 D_view = 2.058 g / cc, D_total = 2.041 g / cc. Like many other substituted benzoic acids, it also forms double associative molecules with symmetric centers by hydrogen bonding. Hydrogen bond length 2.62A, benzene ring and double polycarboxylate plane intersection about 15 °. The average bond length of benzene ring 1.38A, the average bond angle 119.9 °. The thickness of the benzene ring is about 3.7 A The shortest I-I distance between atoms is 2.91A.
