    exchange rates can be rationalized by an analogue of the inner-sphere reorganization energy. Both Ir(III) and Ir(V) are pyramidal and can form pyramidal iridium(IV) with little energetic cost in an orbitally allowed linear approach. Conversely, pyramidalization of the planar tris(imido)osmium(VI) fragment requires placing a pair of electrons in an antibonding orbital. The unique propensity of (mes)3Ir=O

Ir(mes)(3) binds PPh(3) reversibly (K(assoc) = 84 +/- 3 M(-1) in toluene at 20 degrees C) to form an unsymmetrical, sawhorse-shaped four-coordinate complex, whose temperature-dependent NMR spectra reveal a variety of dynamic processes.

    Interaction of N 3 R with Ir(mes) 3 (mes = mesityl, C 6 H 2 Me 3 -2,4,6) gave products dependent on the nature of the azide. When R = mes, the tetrazenido amide complex 1 is obtained in which dehydrogenative coupling of the mesityl groups via the o-methyls has occurred; thermolysis of 1 in toluene resulted in cleavage of the tetrazene ring and formation of amide complex 2. When R = Ph, the aryl tetrazenido amide complex 3 is formed. Photolysis of a mixture of N 3 (mes) and [RuCl 2 (PPh 3 ) 3 ] followed by phosphine exchange gave the tetrazene complex [Ru II Cl 2 N 4 (mes) 2 }(PMe 3 ) 2 ] 4. Thermal reaction of [RuCl 2 H 2 (PPr i 3 ) 2 ] with N 3 (mes) gave the triazenophosphorane complex [RuCl 3 (PPr i 3 )N 3 (mes) PPr i 3 }] 5. The ruthenium allyl amide [Ru(PMe 3 ) 3 NHC 6 H 3 Pr i (η 3 -CH 2 CCH 2 )}] 6 bearing a new hybrid ligand was obtained by interaction of trans-[RuCl 2 (PMe 3 ) 4 ] with Li[NH(C 6 H 3 Pr i 2 -2,6)] in di-n-butyl ether. Plausible reaction mechanisms accounting for the formation of the new compounds are proposed. Finally, the crystal structures of the complexes 1–6 have been determined. Complexes 1 and 2 have pseudo-square planar geometries involving the olefin formed by the coupled methyl groups of two mesityls and three (1) or two (2) amide nitrogens and a chlorine atom (2). Compound 3 has a trigonal bipyramidal metal centre with the axial Ir–N amide bonds longer than the equatorial ones; 4 has an octahedral structure with a bidentate tetragonal ligand and trans phosphines whilst 5 is distorted octahedral with a N,N-chelating phosphazide ligand. Complex 6 is also octahedral with the allyl groups occupying cis sites and the three Ru–P bonds in a facial arrangement.
