Abstract
Abstract The crystal structures of few solvates of 2-(3-methylene-1,3,7-trioxo-6-(2-carboxy-phenyl)-3,5,6,7-tetrahydro-1H-pyrrolo[3,4-f]isoindol-2-yl)benzoic acid (A) namely A·4H2O; A·2DMF; A·2Py; A·3Py are determined (where Py = pyridine, DMF = dimethylformamide). The crystal structure of the hydrated form has Z′ = 0.5, whereas other solvates with DMF and pyridine has Z′ = 1. The neighboring host molecules in the crystal lattices of these solvates have different orientations; these orientations are related by translation or translation cum rotation of the orientation to the neighboring host molecules that has the most symmetric structure.
