A new polymorph of (2,3)-2-amino-3-methyl-penta-noic acid, l-isoleucine CHNO, crystallizes in the monoclinic space group 2 with four independent mol-ecules in the asymmetric unit. The mol-ecules are . In the crystal, N-H⋯O hydrogen bonds link two pairs of independent mol-ecules and their symmetry-related counterparts to form two types of layers stacked in an manner parallel to (001). The hydro-phobic aliphatic isopropyl groups protrude from these layers.
（2,3）-2-氨基-3-甲基戊酸（L-异亮氨酸，化学式为CHNO）的一种新多晶型物在单斜空间群P2中结晶，不对称单元中有四个独立分子。分子……在晶体中，N-H⋯O氢键连接两对独立分子及其对称相关分子，形成两种类型的层，以平行于（001）的方式堆叠。疏水的脂肪族异丙基从这些层中突出。 （原文部分内容缺失，翻译可能存在部分不连贯）
