Reactions of phthalazine, quinazoline, 4,7-phenanthroline and 2,3?-bipyridine with ruthenium carbonyl
The reactions of [Ru3(CO)12] with four aromatic diazines have been studied in THF at reflux temperature. With phthalazine (L1), the compound [Ru3(mu-kappa2N 2N3-L1)(mu-CO)3(CO)7] (1), which contains an intact phthalazine ligand in an axial position bridging an Ru-Ru edge through both N atoms, is initially formed but it reacts with more phthalazine to give [Ru3(kappaN2-L1)(mu- kappa2N2N3-L1)(mu-CO) 3(CO)6] (2), in which a pi-pi stacking interaction between the aromatic rings of both ligands determines their position in cluster axial sites on the same face of the Ru3 triangle. With quinazoline (HL2), the cyclometalated hydrido decacarbonyl derivative [Ru 3(mu-H)(mu-kappa2N3C4-L 2)(CO)10] (3) is initially produced but it partially decarbonylates under the reaction conditions to give [Ru6(mu-H) 2(mu-kappa2N3C4-L 2)(mu3-kappa3-N1N 3C4-L2)(CO)19] (4), which results from the displacement of a CO ligand of 3 by the uncoordinated N1 atom of another molecule of 3. With 4,7-phenanthroline (H2L 3), the stepwise formation of the cyclometalated derivatives [Ru 3(mu-H)(mu-kappa2N4C3-HL 3)(CO)10] (5) and two isomers of [Ru6(mu-H) 2(mu4-kappa4N4C 3N7C8-L3)(CO)20] (6a, 6b) takes place. In compounds 6a and 6b, two Ru3(mu-H)(CO) 10 trinuclear units are symmetrically (C2 in 6a or C S in 6b) bridged by a doubly-cyclometalated 4,7-phenanthroline ligand. With 2,3?-bipyridine (HL4), two products have been isolated, [Ru3(mu-H)(mu-kappa2N 3?C4?-L4)(CO)10] (7) and [Ru3(mu-H)(mu-kappa3N2N 3?C2?-L4)(CO)9] (8). While compound 7 contains an N3?C4?- cyclometalated 2,3?-bipyridine, in compound 8 an N 3?C2?-cyclometalation is accompanied by the coordination of the N2 atom of the remaining pyridine fragment. The structures of compounds 2, 3, 4, 6a and 8 have been determined by X-ray diffraction crystallography.
