The trinuclear gallium-bridged Ferrocenophane [{Fe(eta5-C5H4)2}3Ga2]: synthesis, bonding, structure, and coordination chemistry.

The trinuclear ferrocenophane [{Fe(eta(5)-C(5)H(4))(3)}(2)Ga(2)] (3) featuring two sp(2)-hybridized gallium atoms in bridging positions between three ferrocene-1,1'-diyl units represents a novel type of ferrocene derivative. Compound 3 is obtained by thermal treatment of 1,1'-bis(dimethylgallyl)ferrocene (1) in nondonor solvents or in diethyl ether as solvent and subsequent thermal decomplexation. The [1.

[{Fe(C H ) } {Ga(C H N)} ]: A Trinuclear Gallium-Bridged Ferrocenophane with a Carousel Structure.

A molecular carousel, that is the appearance of the structure of the title compound [1⋅2 py], the first complex of a new structure type prepared by a highly selective condensation reaction from the equally new complex [Fe(C H GaMe ) ]. The first gallium bridged [m.m]ferrocenophane [{Fe(C H ) } {GaMe(C H N)} ] is formed as an intermediate; this compound can also be prepared in a planned synthesis and can be converted into [1⋅2 py] by warming.
