Sumario: | The synthesis and characterization of two heterobimetallic complexes [K([18]crown‐6){(η(4)‐C(14)H(10))Fe(μ‐η(4):η(2)‐P(4))Ga(nacnac)}] (1) (C(14)H(10) = anthracene) and [K(dme)(2){(η(4)‐C(14)H(10))Co(μ‐η(4):η(2)‐P(4))Ga(nacnac)}] (2) with strongly reduced P(4) units is reported. Compounds 1 and 2 are prepared by reaction of the gallium(III) complex [(nacnac)Ga(η(2)‐P(4))] (nacnac = CH[CMeN(2,6‐iPr(2)C(6)H(3))](2)) with bis(anthracene)ferrate(1–) and ‐cobaltate(1–) salts. The molecular structures of 1 and 2 were determined by X‐ray crystallography and feature a P(4) chain which binds to the transition metal atom via all four P atoms and to the gallium atom via the terminal P atoms. Multinuclear NMR studies on 2 suggest that the molecular structure is preserved in solution. |
