Rare earth chemistry has witnessed remarkable advances in recent years. In particular, ancillary ligands other than cyclopentadienyl derivatives have been introduced to the organometallic chemistry and their complexes exhibit distinct reactivity and properties compared to the metallocene or half-sandwiched analogues. The present chapter reviews arene-bridged rare earth complexes with an emphasis on those compounds obtained by reduction reactions. A particular emphasis is placed on rare earth complexes supported by 1,1′-ferrocenediyl diamides since they show the most diverse chemistry with arenes: fused arenes, such as naphthalene and anthracene, formed inverse-sandwiched complexes, in which the arene is dianionic; weakly conjugated arenes, such as biphenyl, p-terphenyl, and 1,3,5-triphenylbenzene, were unexpectedly reduced by four electrons and led to 6-carbon, 10- electron aromatic systems; on the contrary, (E)-stilbene, which has a carbon-carbon double bond between the two phenyl rings, could only be reduced by two electrons, which were located on the carbon-carbon double bond instead of the phenyl rings.

“…[15] If one goes from the small to the larger neutral P n molecules, then P 20 , the allphosphorus analogue of the Paquettes (CH) 20 dodecahedron (a platonic solid with 12 pentagons, 20 vertices, and 30 edges) represents a modification of phosphorus, the search for which should not be a search for utopia, particularly since theory predicts that P 20 lies energetically only slightly above the value for 5 Â P 4 units.…”

Neutral P6 can be generated in the gas phase from CpP6 and detected by mass spectrometry. Small, neutral Pn molecules, apart from white phosphorus (tetrahedral P4) are scarce. The picture shows the P6 isomers that are isoelectronic to the five (CH)6 valence isomers. The calculated stability decreases from left to right; thus a benzvalene structure (far left) is assumed for the P6 molecule detected in the gas phase. Futhermore, the predictions from theory as well as the complex chemical stabilization of small Pn molecules are presented.
