The Reaction of μ-dithiobis(tricarbonyliron) with dimanganese decacarbonyl: a novel product and an interesting structural problem

Abstract The photo-induced reaction of (μ-S2)Fe2(CO)6 and Mn2(CO)10 in tetrahydrofuran solution gave a complex of composition S2Fe2Mn2(CO)14. A combination of X-ray crystallography, Mossbauer spectroscopy, mass spectroscopy and elemental analysis established this composition and the structure as Fe2Mn(CO)9(μ3-S)(μ4-S)Mn(CO)5, the Fe2Mn system of which contains one Feue5f8Fe and one Feue5f8Mn bond.

The reactivity of [Au(CH2)2PPh2]2(1) with CCl4. The oxidative addition of CCl4 to a dimeric gold ylide complex to give AuII and AuIII CCl3 adducts. The X-ray crystal structure of [Au(CH2)2PPh2]2Cl2, [Au(CH2)2PPh2]2(CCl3)Cl, and [Au(CH2)2PPh2]2(CCl3)Cl3

Prolonged reaction of [Au(CH2)2PPh2]2(1) with CCl4 gives [Au(CH2)2PPh2]2Cl2(2), [Au(CH2)2PPh2]2(CCl3)Cl (3) being formed initially, and the reaction of (1) with tetrahydrofuran-CCl4(1 : 5) gives [Au(CH2)2PPh2]2(CCl3)Cl3(4), an example of a new class of dimeric gold(III)–alkyl halide complex; the X-ray crystal structures of (2), (3), and (4) are described.
