“…On the other hand, coordination chemistry of heavy Cps is similar to that of the lighter analogues (Cps). 13 This is in sharp contrast to the fact that all the metallole rings in the Si and Ge analogues of Cpreported to date are almost planar and coordinate the transition metals in η 5 -fashions. However, our findings reported here defy this common knowledge: coordination modes of tin analogues of Cpare highly dependent on a substituent on the tin atom.…”

Reactions of an anionic heavy ruthenocene with CCl4, MeI, EtBr and Me3SiCl afforded the first stannole monoanion complexes. Surprisingly, coordination modes of the stannole rings are highly dependent on the substituents on the tin atom. The chloro derivative exhibits a η(4)-fashion-like coordination mode with a bent stannole ring, whereas the trimethylsilyl derivative adopts the conventional η(5)-coordination mode. Coordination modes of the alkyl derivatives are in between the two types. Cyclic voltammograms for these complexes reveal that the electron-donating character of the stannole ligand becomes stronger as the stannole ring becomes planar. Theoretical calculations elucidate that the different coordination modes originate from both electronegativity of an adjacent atom to the tin atom and bulkiness of a substituent on the tin atom.

“…In contrast, the reaction of [Cp*Fe(h 5 -P 5 )] with [{Cp*Ir(CO)} 2 ] transforms the planar P 5 ligand into a folded cyclo-P 5 envelope (77), which, after addition of a second iridium complex, is definitely cleaved to a P 5 chain (78) (Scheme 12) [98].…”

Dedicated to Professor Otto J. Scherer on the occasion of his 68th birthday A critical survey of the coordination chemistry of white phosphorus illustrating the metalmediated degradation of the P 4 tetrahedron is presented. The underlying principles to account for the activation and stepwise fragmentation of this molecule in the presence of transition metal complexes are presented with emphasis given to mechanistic aspects. A collection of 31 P-NMR spectral data for the known polyphosphorus P x compounds (x £ 4) is also presented and briefly commented.
