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 group Pnma. They are connected to each other by C-H···O hydrogen bonds, forming two-dimensional layers parallel to the ac plane. In addition, Cl···Cl and π-π interactions link adjacent molecules in different layers, thus forming zigzag ribbons along the b axis, such that a three-dimensional architecture is generated.
标题化合物1,4 - 萘醌,2 - 二氯甲基 - 3 - 甲基 - 1,4 - 二氢萘 - 1,4 - 二酮,化学式为C₁₂H₈Cl₂O₂,是维生素K₃的一种氯化衍生物,维生素K₃是一种合成化合物,也被称为甲萘醌。(I)的分子是平面的,位于空间群为Pnma的晶体学镜面(Z' = 0.5)上。它们通过C - H···O氢键相互连接,形成平行于ac平面的二维层。此外,Cl···Cl和π - π相互作用连接不同层中的相邻分子,从而沿着b轴形成锯齿状带,进而产生三维结构。
