Fe—S—Mo Clusters and their Relations to the Fe—Mo-Cofactor of Nitrogenase. I. Preparation and Crystal Structure of Compounds with the Complex Anions [Cl2FeS2MoS2]2- and [Cl2FeS2WS2]2-The preparation and characterization of R1R2[Cl2FeS2MoS2] (1) and R1R2-[Cl2FeS2WS2] (2) has been described. The compounds are isostructural and crystallize in the space group P1 with Z = 2 (for details see Inhaltsübersicht).
Notes:
Die Darstellung und röntgenographische Charakterisierung von R1R2-[Cl2FeS2MoS2] (1) und R1R2[Cl2FeS2WS2] (2) wird beschrieben. (R1 = PPh4, R2 = N(CH3)3(CH2Ph)). Die Verbindungen sind isostrukturell und kristallisieren in der Raumgruppe P1 mit Z = 2 (Gitterdimensionen von 1: a = 13,224(5), b = 14,978(2), c = 10,042(2) Å, α = 82,07(2), β = 81,72(3), γ = 74,41(2)°; von 2: a = 13,263(3), b = 15,051 (3), c = 10,087(2) Å, α = 82,07(2), β = 81,69(2), γ = 74,44(2)°). Der Fe—Mo-Abstand von 1 (2,775 Å) ist vergleichbar mit entsprechenden Abständen in der Nitrogenase.
