    Description / Table of Contents: Niobium and Tantalum Complexes with P2 and P4 LigandsThe photolysis of [Cp″Ta(CO)4] 1 (Cp″ = C5H3tBu2-1,3) and P4 affords Cp″(CO)2Ta(η4-P4) 2, [{Cp″(CO)Ta}2(m̈-η2:2-P2)2] 3 and [Cp3″(CO)3Ta3(P2)2] 4. In a photochemical reaction 2 and [Cp*Nb(CO)4] 5 form [{Cp*(CO)Nb}{Cp″(CO)Ta}(m̈-η2:2-P2)2] 6 and [{Cp*(CO)2Nb} {Cp*Nb}{Cp″(CO)Ta}(m̈3-η2:1:1-P2)2] 7, a compound with the novel m̈3-η2:2:1-P2-coordination mode. The reaction of 2 and [Cp*Co(C2H4)2] 8 leads to [{Cp*Co} {Cp″(CO)Ta}(m̈-η2:2-P2)2] 9, a heteronuclear complex with an „early“ and a „late“ transition metal. Complexes 2, 3, 7 and 9 have been further characterized by X-ray structure analyses.
    Notes: Die Photolyse von [Cp″Ta(CO)4] 1 (Cp″ = C5H3tBu2-1,3) und P4 ergibt [Cp″(CO)2Ta(η4-P4)] 2, [{Cp″(CO)Ta}2(μ-η2:2-P2)2] 3 und [Cp3″(CO)3Ta3(P2)2] 4. 2 reagiert photochemisch mit [Cp*Nb(CO)4] 5 zu [{Cp*(CO)Nb}{Cp″(CO)Ta}(m̈-η2:2-P2)2] 6 und [{Cp*(CO)2Nb}{Cp*Nb} {Cp″(CO)Ta}(m̈3-η2:1:1-P2)2] 7, einer Verbindung mit der neuen m̈3-η2:2:1-P2-Koordinationsvariante. Die Reaktion von 2 und [Cp*Co(C2H4)2] 8 führt zum heteronuklearen Komplex [{Cp*Co} {Cp″(CO)Ta}(m̈-η2:2-P2)2] 9 mit einem „frühen“ und „späten“ Übergangsmetall. Die Komplexe 2, 3, 7 und 9 wurden zusätzlich durch eine Röntgenstrukturanalyse charakterisiert.

    Description / Table of Contents: Heterometallic Complexes with E6 Ligands (E = P, As)The reaction of [Cp*Co(μ-CO)]2 1 with the sandwich complexes [Cp*Fe(η5-E5)] 2 a: E = P, 2 b: E = As in decalin at 190°C affords besides [Cp2*Co2E4] 4: E = P, 7: E = As and [Cp2*Fe2P4] 5 the trinuclear complexes [(Cp*Fe)2(Cp*Co)(μ-η2-P2)(μ3-η1:2:1-P2)2] 3 as well as [(Cp*Fe)2(Cp*Co)(μ3-η2:2:2-As3)2] 6. With [Mo(CO)5(thf)] 3 and 6 form in a build-up reaction the tetranuclear clusters [(Cp*Fe)2(Cp*Co)E6{Mo(CO)3}] 10: E = P, 11: E = As. 3, 6 and 11 have been further characterized by an X-ray crystal structure determination.
