Au-π interaction between the electron-rich aromatic ring and a gold (I) ions, such as phenyl group
is that of the interaction acting. In general, the distance between the gold (I) ion and the aromatic ring center
is 4.0 Å when the approaches to, and with respect to an axis perpendicular to the aromatic ring of gold (I) ions and aromatic
angle between the ring center than the 20 ° Sometimes, it has been reported that Au-π interaction is expressed
that. This interaction is known to be expressed in gold (III) ions as well as gold (I) ions
are, by Au-π interaction works in the crystal, the metal complex is stable
to form a cohesive structure It has been revealed. Therefore, Oya-kin interact with and
monitor Au-π interaction has the form aggregated structures in a novel supramolecular aggregates or crystals
as may become a driving force of the eye, drawing attention there.
