The new Ag8{Fe(CO)4}4(dppm)2 and Ag4Au4{Fe(CO)4}4(P∧P) 2 (P∧P = dppm, dppe) neutral cluster compounds have been isolated in good yields by condensation in CH3CN or THF of M2(P∧P)2+ (M = Ag, Au) cations with [Ag4{Fe(CO)4}4]4- anions and characterized by IR, NMR, and microanalyses. The structure of both Ag8{Fe(CO)4}4(dppm)2 and Ag4Au4{Fe(CO)4}4-(dppe)2 has been determined by X-ray diffraction studies. The former represents a very rare example of a neutral Ag-Fe cluster containing phosphine as ancillary ligand for silver.

Abstract
The new Ag8{Fe(CO)4}4(dppm)2 and Ag4Au4{Fe(CO)4}4(P∧P) 2 (P∧P = dppm, dppe) neutral cluster compounds have been isolated in good yields by condensation in CH3CN or THF of M2(P∧P)2+ (M = Ag, Au) cations with [Ag4{Fe(CO)4}4]4- anions and characterized by IR, NMR, and microanalyses. The structure of both Ag8{Fe(CO)4}4(dppm)2 and Ag4Au4{Fe(CO)4}4-(dppe)2 has been determined by X-ray diffraction studies. The former represents a very rare example of a neutral Ag-Fe cluster containing phosphine as ancillary ligand for silver.File in questo prodotto:
