Abstract
[5]Trovacenol (<b>4</b><sup>•</sup>) prepared according to the\nsequence (C<sub>7</sub>H<sub>7</sub>)V(C<sub>5</sub>H<sub>5</sub>) (<b>1</b><sup>•</sup>)→ (C<sub>7</sub>H<sub>7</sub>)V(C<sub>5</sub>H<sub>4</sub>OSiMe<sub>3</sub>) (<b>5</b><sup>•</sup>)\n→ (C<sub>7</sub>H<sub>7</sub>)V(C<sub>5</sub>H<sub>4</sub>OH) (<b>4</b><sup>•</sup>) in the crystal adopts a sheet\nstructure. The sheets consist of parallel chains of hydrogen bonds, graph set C(4), to which the [5]trovacenyl\ngroups are connected, forming double layers. Packing of\nthe trovacene units on both sides of the (···O−H···O−H···)<i><sub>n</sub></i> spines displays a herringbone pattern. In this way\nO−H···O as well as (C<sub>7</sub>H<sub>7</sub>)H···π(C<sub>5</sub>H<sub>5</sub>) hydrogen bonding\nis optimized. This study represents the first full structural characterization of a metallocenol.
