Summary The degradation-resistant ligand tri-2-pyridylamine (tripyam) (1) forms a variety of stable ruthenium complexes. Reaction of (1) with RuCl2(PPh3)3 yields the complex RuCl2(PPh3)(tripyam) (2) and, upon prolonged heating in pyridine, forms RuCl2(py)(tripyam) (3). Complexes (2) and (3) display unusual thermal stability, resisting degradation at temperatures of 270 °C. Reaction of (2) with two equivalents of AgSbF6 in water yields the solvento complex [Ru(PPh3)(tripyam)(OH2)2] (SbF6)2 (2a). Reaction of (1) with RuCl3·H2O also yields the trichloro complex RuCl3(tripyam) (4). The organometallic precursor [RuCl2(p-cymene)]2 reacts with (1) and either two or four equivalents of AgSbF6 to yield [RuCl(p-cymene)(η 2-tripyam)]SbF6 (5) and [Ru(p-cymene) (η 3-tripyam)](SbF6)2 (6), respectively. Each of these complexes has been characterized by spectroscopic techniques and, in the case of (5), by single-crystal X-ray diffraction.
