The title compound, a precursor for polymeric terpyridine derivatives, exhibits near-coplanar pyridine rings. Steric hindrance from a close H.H contact forces the vinyl group out of plane.

Area of Science:

  • Coordination Chemistry
  • Organic Synthesis
  • Supramolecular Chemistry

Background:

  • Terpyridine derivatives are crucial ligands in coordination chemistry.
  • Polymeric terpyridine complexes have applications in materials science.
  • Understanding molecular geometry is key to designing novel functional materials.

Purpose of the Study:

  • To characterize the molecular structure of a novel terpyridine precursor.
  • To investigate the conformational properties of the terpyridine moiety and vinyl group.
  • To provide insights into the synthesis of related polymeric terpyridine derivatives.

Main Methods:

  • Single-crystal X-ray diffraction analysis was performed.
  • Structural parameters including bond lengths, bond angles, and torsion angles were determined.

  • Intermolecular interactions were analyzed.
  • Main Results:

    • The title compound, C(17)H(13)N(3), was synthesized and structurally characterized.
    • The molecule displays transoid and near-coplanar pyridine rings.
    • A close H.H contact between the vinyl group and the terpyridyl moiety forces the vinyl group out of the plane.

    Conclusions:

    • The studied terpyridine precursor possesses a unique molecular conformation.
    • This structural feature may influence its reactivity and coordination behavior.
    • The findings aid in the rational design of new polymeric terpyridine-based materials and metal complexes.
