“…Only a small number of these species contain two of these m -terphenyl substituents, which is arguably due to their rather difficult preparation. Examples include species of the elements Mn, , Fe, ,, Co, ,, Zn, − Cd, , Hg, ,, Al, , Ga, − In, Tl, Ge, − Sn, ,,,, Pb, , and Bi, the majority of which are low-coordinate and/or contain heavier elements possessing larger atomic radii. While mono( m -terphenyl)silanes are abundantly known, − to the best of our knowledge there is no reported case of bis( m -terphenyl)silanes.…”
