Molecular orbital analysis of the bonding in low nuclearity gold and platinum tertiary phosphine complexes and the development of isolobal analogies for the M(PR 3) fragment

The stoichiometries and geometries of gold and platinum tertiary phosphine cluster compounds of the type M n (PR 3) n x+ ( n = 3–6) have been analysed using extended Hückel molecular orbital calculations. The isolobal nature of the M(PH 3) fragment depends critically on the nature of the metal atom M, and may be used to provide a basis for predicting a wide spectrum of homo- and hetero-nuclear metal cluster compounds.

Heteronuclear metal complexes with bridging methoxymetylidyne ligands: X-ray crystal structures of [AuRu3(µ2-COMe)(CO)10(PPh3)] and [Fe3Pt(µ3-H)(µ3-COMe)(CO)10(PPh3)

Heteronuclear cluster compounds can be prepared from reactions between [M3(µ-H)(µ-COMe)(CO)10](M = Fe or Ru) and [ AuMePPh3], or between the tri-iron compound and [Pt(C2H4)2(PPh3)]; the structures of [AuRu3(µ2-COMe)(CO)10(PPh3)] and [Fe3Pt(µ3-H)(µ3-COMe)(CO)10(PPh3)] have been established by X-ray diffraction.

Polynuclear tungsten-iron, -ruthenium and -osmium carbonyl complexes: crystal structures of [FeW2(µ3-C2R2)(CO)6(η-C5H5)2], [OsW2(µ3-C2R2)(CO)7-(η-C5H5)2](two isomers), and [Os3W(µ3-CR)(CO)11(η-C5H5)](R = C6H4Me-4)

Reactions of polynuclear carbonyl complexes of iron, ruthenium, or osmium with [WCR(CO)2(η-C5H5)](R = C6H4Me-4) afford several heteronuclear metal cluster compounds, and the structures of [FeW2(µ3-C2R2)(CO)6(η-C5H5)2], [Os3W(µ3-CR)(CO)11(η-C5H5)], and [OsW2(µ3-C2R2)(CO)7(η-C5H5)](two isomers) have been established by X-ray diffraction.

Neue hetero-cluster mit FeCo 2-, MoCo 2- und FeMoCo-gerüst

The heteronuclear cluster compounds (PhP)FeCo 2 (CO) 9, (PhP)MoCo 2 Cp(CO) 6(μ-AsMe 2 and (PhP)FeMoCoCp(CO) 8 have been prepared via a reaction sequence originally developed for the formation of FeCo 2, MoCo 2 and FeMoCo frameworks. (PhP)FeMoCp(CO) 8 is a chiral complex due to the four different framework units.

New substituted heteronuclear cluster carbonyls containing platinum and a metal from the Fe, Ru, Os triad

Low-valent phosphine–platinum complexes react with Fe2(CO)9, Ru3(CO)12, or H2Os(CO)4 to give heteronuclear cluster compounds of the types Fe2Pt(CO)10-nLn(n= 1 or 2), MPt2(CO)5L3, and M2Pt(CO)7L3(M = Ru, Os); the ligand L may be any one of a variety of substituted phosphines or phosphites, or triphenylarsine.
