The synthesis and characterization of two heterobimetallic complexes [K([18]crown-6){(eta(4)-C14H10)Fe(mu-eta(4):eta(2)-P-4)Ga(nacnac)}] (1) (C14H10 = anthracene) and [K(dme)(2){(eta(4)-C14H10)Co(mu-eta(4):eta(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(eta(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.
