Deskripsi
Complexation of the 8,8′-bis(methylsulfanyl) derivatives of cobalt and iron bis(dicarbollides) [8,8′-(MeS)<sub>2</sub>-3,3′-M(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>]<sup>−</sup> (M = Co, Fe) with copper, silver, palladium and rhodium leads to the formation of the corresponding chelate complexes, which is accompanied by a transition from the <i>transoid</i> to the <i>cisoid</i> conformation of the bis(dicarbollide) complex. This transition is reversible and can be used in design of coordination-driven molecular switches based on transition metal bis(dicarbollide) complexes. The solid-state structures of {(Ph<sub>3</sub>P)ClPd[8,8′- (MeS)<sub>2</sub>-3,3′-Co(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>-κ<sup>2</sup>-S,S′]} and {(COD)Rh[8,8′-(MeS)<sub>2</sub>-3,3′-Co(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>-κ<sup>2</sup>-S,S′]} were determined by single crystal X-ray diffraction.
