The organometallic complexes of general formulae [Me2Ga{η 2-E,E′-[R2P(E)NP(E′)R′2]}] [R = R′ = Ph, E = E′ = O (1); R = R′ = Ph, E = E′ = S (2); R = R′ = Ph, E = E′ = Se (3); R = R′ = Ph, E = O, E′ = S (4); R = Me, R′ = Ph, E = S, E′ = O (5)] and [Me 2Ga{η2-S,S′-[Ph2P(S)NC(S)(C 9H10N)]}] (6) were obtained by facile methane elimination reactions from GaMe3 and the acidic ligands L1H [(XPPh2)2NH (X = O, S, Se)1 (OPPh2)(SPPh 2)NH, and (OPMe2)(SPPh2)NH] and L2H [Ph2P(S)NHC(S)(C9H10N)] in toluene. Replacement of one phosphorus atom by a carbon atom in the ligand skeleton of L 1H gave the new ligand L2H, which, upon reaction with GaMe3, gave compound 6, which shows no significant structural differences with respect to 1-5. Therefore, L2H does not induce partial planarity in the six-membered ring, indicating the necessity for replacing both phosphorus atoms of the ligand by carbon atoms, as in the β-diketonate-type derivatives, in order to impose ring planarity. Thus, despite originating from a variety of ligands with differing donor atoms and substituents at the phosphorus atoms, all complexes show little structural differences. Wiley-VCH Verlag GmbH & Co.
