Abstract
The coumarin ring system in the title compound, C(15)H(18)O(5) [IUPAC name: 8-(2,3-dihydr-oxy-3-methyl-butyl)-7-meth-oxy-2H-1-benzopyran-2-one], isolated from Muraya paniculata, is planar (r.m.s. deviation 0.017 Å). In the crystal, the two hydr-oxy groups are involved in O-H⋯O hydrogen bonding with adjacent mol-ecules, forming a sheet structure.
摘要
从九里香中分离得到的标题化合物C(15)H(18)O(5) [IUPAC名称：8-(2,3-二羟基-3-甲基丁基)-7-甲氧基-2H-1-苯并吡喃-2-酮]中的香豆素环系统是平面的（均方根偏差为0.017 Å）。在晶体中，两个羟基与相邻分子形成O-H⋯O氢键，形成层状结构。
