Synthesis and structural studies of the iron "sandwich" complex [Fe(η5-C5Me5)(η5-C3tBu3P2)] 1 are described. The lone pair electrons of the two adjacent phosphorus atoms of the C2tBu2P3 ring in the triphospha-ferrocene complex [Fe(η5-C5Me5)(η5-C2tBu2P3)] 2 can ligate to other metal centres. The results of single crystal X-ray structural studies of the molybdenum and tungsten pentacarbonyl η1-complexes [Fe(η5-C5Me5)(η5-C2tBu2P3)M(CO)5] (4: M = Mo, 5: M = W) are discussed; they form an isostructural series with the previously reported chromium complex. The starting material 2 reacts with [(C5H4Me)(CO)2Mn(THF)] to form the adduct [Fe(η5-C5Me5)(η5-C2tBu2P3)Mn(CO)2(η5-C5H4Me)] 6. The phenyl-substituted di-and triphosphacyclopentadienides [Na(DME)3][C3Ph3P2] and [Na(DME)3][C2Ph2P3] (DME = 1,2-dimethoxyethane) react with ferrous chloride and Li[C5Me5] to give the 'sandwich' compounds [Fe(η5-C5Me5)(η5-C3Ph3P2)] 9 and [Fe(η5-C5Me5)(η5-C2Ph2P3)] 10. The latter reacts with W(CO)5(THF) to yield the η1-complex [Fe(η5-C5Me5)(η5-C2Ph2P3)W(CO)5] 11.

He(I) photoelectron spectra of the phospha-alkynes ButCP and PhCP have been obtained.The spectra have been assigned by comparison with spectra of related species and with the aid of ab initio SCF molecular orbital calculations.The first ionisation potentials are 9.61 and 8.68 eV for ButCP and PhCP respectively.These correspond to electron removal from orbitals with essentially ?(CP) bonding character.

The PE spectroscopic optimization of thermal decomposition reactions in the gaseous phase has been applied to the chlorophosphane derivatives RC=PCl with R = C6H5, Si(CH3)3.In a short-path pyrolysis, (H3C)3SiCl is split off quantitatively at 1300 K.The methylidynephosphanes formed, (H3C)3Si-CP and C6H5-CP, can be detected and characterized by comparison of their PE spectra with that of the stable tert-butyl derivative, (H3C)3C-CP.
