摘要：

To provide crystal polymorphs of 4-[5-(pyridin-4-yl)-1H-1,2,4-triazol-3-yl]pyridine-2-carbonitrile, which is a useful pharmaceutical, and a production method therefor. Through purification of a corresponding salt, recrystallization, or storage under humidified conditions, three different crystal forms； i.e., crystalline polymorphs of 4-[5-(pyridin-4-yl)-1H-1,2,4-triazol-3-yl]pyridine-2-carbonitrile are produced.
