The title 1,4-naphthoquinone, 2-dichloromethyl-3-methyl-1,4-dihydronaphthalene-1,4-dione, C12H8Cl2O2, is a chlorinated derivative of vitamin K3, which is a synthetic compound also known as menadione. Molecules of (I) are planar and lie on a crystallographic mirror plane (Z′ = 0.5) in the space groupPnma. They are connected to each other by C—H...O hydrogen bonds, forming two-dimensional layers parallel to theacplane. In addition, Cl...Cl and π–π interactions link adjacent molecules in different layers, thus forming zigzag ribbons along thebaxis, such that a three-dimensional architecture is generated.
标题中的 1,4-萘醌,即 2-二氯甲基-3-甲基-1,4-二氢萘-1,4-二酮,C12H8Cl2O2,是维生素 K3 的氯化衍生物,是一种合成化合物,也称为 menadione。(I)的分子是平面的,位于空间群 Pnma 的结晶镜面上(Z′=0.5)。它们通过 C-H...O 氢键相互连接,形成平行于晶面的二维层。此外,Cl......Cl 和 π-π 相互作用将不同层中的相邻分子连接起来,从而沿轴向形成之字形带,这样就产生了一个三维结构。
