2-Iodo­aniline at 100 K

In the crystal structure of the title compound, C₆H₆IN, each 2-iodo­aniline mol­ecule forms part of three extended helices. Each helix exhibits a different inter­molecular inter­action, viz. weak N—H...N hydrogen bonds with an H...N distance of 2.31 (11) Å, I...I inter­actions of 3.7986 (15) Å and C—H...π contact distances of 2.53 Å.

2-Phenoxy­benzoic acid at room temperature

In the crystal structure of the title compound, C₁₃H₁₀O₃, the mol­ecules form classical hydrogen-bonded carboxylic acid dimers [O...O = 2.651 (2) Å]. These dimers are linked by C—H...π and π–π inter­actions to give a three-dimensional network.
