Abstract
The interaction of Mo(CO)6 and Ru3(CO)12 with 2-aminoethylpyridine (aepy), 2-hydrazinopyridine (hzpy) and dipicolylamine (dpa) have been investigated. Molybdenum complexes were found to have either mono- or binuclear derivatives, [MoO2(CO)2(aepy)] (1), [MoO2(CO)2(hzpy)] (2), [Mo2O6(aepy)2] (3), [Mo2O6(hzpy)2] (4), and [Mo2O4(dpa)2] (5), depending on the reactions conditions. Ruthenium complexes are shown to have a molecular formulae of a mononuclear species; [Ru(CO)3(aepy)] (6), [Ru(CO)3(hzpy)] (7) and [Ru(CO)2(dpa)] (8). The proposed structures of the complexes were elucidated using elemental analyses, i.r., u.v.–vis. and n.m.r. spectroscopy. The thermal stabilities of the reported complexes were also investigated using the t.g. technique.
