Article Synopsis
- The compound CHClNO has two independent molecules in its asymmetric unit, each with distinct conformations of various rings.
- Both molecules feature an internal C-H⋯N hydrogen bond and display disordered oxygen atoms in the nitro groups and a chlorine atom.
- The molecules are interconnected by C-H⋯O and C-H⋯π hydrogen bonds, resulting in a three-dimensional supra-molecular structure.
