Die Struktur von Ph-P[C5H5(CO)2MnFe2(CO)6]. Ein Komplex mit einem verbrückenden μ3-Ph-P-Liganden.

Abstract

The title compound, which may be prepared from C5H5(CO)2Mn—P(Ph)Cl2 and Fe2(CO)9 crystallizes in the monoclinic space group C 2/c with a = 1579(2), b = 1592(2), c = 1790(3) pm, β = 97.2(1)°, Z = 8. The structure was solved by direct methods. Full matrix refinement led to R1= 0.066. The compound contains a threemembered metallocycle with two iron and one manganes atoms. Each iron atom bears three terminal carbonyl groups; the two CO-ligands of the C5H5Mn(CO)2 fragment form unsymmetrical bridges with the two iron atoms. The metal triangel is capped by a Ph—P group with a triply bridging phosphorus atom.
