Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>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 (<italic>Z</italic>′ = 0.5) in the space group <italic>Pnma</italic>. They are connected to each other by C—H...O hydrogen bonds, forming two‐dimensional layers parallel to the <italic>ac</italic> plane. In addition, Cl...Cl and π–π interactions link adjacent molecules in different layers, thus forming zigzag ribbons along the <italic>b</italic> axis, such that a three‐dimensional architecture is generated.</p> </abstract>
