Background:
- Understanding molecular geometry is crucial in chemistry.
- Crystal structure analysis provides precise atomic arrangement data.
Purpose of the Study:
- To determine the crystal structure of the title compound, C(18)H(14)N(4).
- To analyze the molecular geometry and symmetry of C(18)H(14)N(4).
Main Methods:
- Single-crystal X-ray diffraction was employed.
- The crystal structure was solved and refined.
Main Results:
- The molecule C(18)H(14)N(4) exhibits site symmetry.
- The centroid of the benzene ring is positioned on an inversion center.
- A small dihedral angle of 2.70(9)° was measured between the pyridine and benzene rings, indicating near planarity.
Conclusions:
- The crystal structure of C(18)H(14)N(4) has been elucidated.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
