4-([1,1′:3′,1′′-terphenyl]-2′-yloxy)-5-chlorophthalonitrile

The study focuses on the synthesis and detailed crystal structure analysis of 4-([1,1′:3′,1′′-terphenyl]-2′-yloxy)-5-chlorophthalonitrile. Using X-ray diffraction methods, the authors achieved the precise refinement of the atomic arrangement, revealing the specific spatial organization of molecules within the crystal lattice. The manuscript thoroughly discusses the key intermolecular interactions—such as hydrogen bonding and π-π stacking—that govern the crystal packing. These interactions play a crucial role in stabilizing the structure and have a direct impact on the material’s physical and chemical properties, including its thermal stability and optical characteristics.
