[As(C6H5)4]2](μ-H)Mn3(μ-CO)2(CO)10] (1) gives the carbonylmanganese clusters [(μ-H)Mn5(CO)17]2− (A2) and [(μ-H)3Mn3(CO)12] (3). Reaction of GaCl3 with K3[Mn3(μ-CO)2(CO)10] (4) yields the cluster dianions [Mn3(CO)12μ-GaCl2}]2− (A5) and [Mn3(CO)12μ-GaCl(OH)}]2− (A6). InCl3 reacts with 4 to give the anionic complexes [Mn2(CO)8μ-InClMn(CO)5}2]2− (A7), [InMn3(CO)12}2]3− (A8) and [(μ5-In)(Mn(CO)4}5]2−

complexes [Fe3(CO)11Au}3−x(triphos)(AuCl)x](3−x)− (x = 0 (8), 1 (9) or 2 (10)) were obtained by the reaction of the trinuclear [Fe3(CO)11]2− anion with [(AuCl)3(triphos)] in the appropriate molar ratio. Attempts to obtain mixed manganeseirongold clusters resulted in a mixture of compounds, the nature of which has been explained in terms of metal-ligand redistribution processes.
The anion radical of Mn3(μ-H)3(CO)12 has been generated in frozen 2-methylte- trahydrofuran solutions by γ-irradiation and its ESR spectra have been analyzed. The spectra are consistent with D3h geometry of the anion radical. The unpaired electron is accommodated in an a′2; MO (D3h point group) constructed mainly from the manganese d AO's and with bent σ★ characteristics with respect to the three MnMn

904(8)Å, and β= 103.57(4)°; R= 0.026 for 2 771 intensities [I 3.0σ(I)]. Reaction of compound (1) with C5H6 in toluene, or thermolysis of the complex trans-[Fe2(µ-CCH2)(µ-CO)(CO)2(η-C5H5)2], gives [Fe3(µ3-CMe)(µ-CO)3(η-C5H5)3]. Treatment of trans-[Fe2(µ-CCH2)(µ-CO)(CO)2(η-C5H5)2] with [Co2(CO)8] in diethyl ether yields as the principal product [Co3Fe(µ4-CCH2)(µ-CO)2(CO)7(η-C5H5)](3). The latter complex was
