摘要：
A third form of benzamide has been characterized 175 years after the first report of polymorphism in benzamide; the metastable silky needlelike form first described by Wohler and Liebig was hiddenfor so long owing to the similarities between the metrics of its unit cell and those of the stable form I (the H-bonding motif is depicted). Selective crystallization techniques taking advantage of modern online sensors were crucial in this work. (Figure Presented) © 2007 Wiley-VCH Verlag GmbH & Co. KGaA."
