摘要：

Two new polymorphs of 4-(N,N-dimethylamino) benzoic acid, C9H11NO2, resulting from the attempted cocrystallization in ethanol of 4-(N,N-dimethylamino) benzoic acid and a mixture of 3-(N, N-dimethylamino) benzoic acid and 3-(3-pyridyl)-2-pyridone producing one polymorph, and a mixture of 3-(N,N-dimethylamino) benzoic acid and 5-methoxy-3,3'-bipyridine producing the second polymorph, have been crystallographically characterized. The primary intermolecular O - H center dot center dot center dot O hydrogen bonds generate a dimeric acid - acid motif that is present in all three polymorphs.
