Abstract
The protonation of RuH(NO)(Cyttp) resulted in the formation of [RuH2(NO)(Cyttp)]+ which is characterized as a classical cis-dihydried complex. This complex is fluxional and the intramolecular process involving a molecular hydrogen complex is proposed. This mechanism was further supported by the reactivity of this complex toward neutral 2-electron ligands. On the other hand, it failed to detect the existence of [RuH2(NO)(etp)]+ probably due to instability of the complex but the crystal structure of [Ru(PMe3)(NO)(etp)]+ formed by the protonation of RuH(NO)(etp) followed by the addition of PMe3 was determined to have a trigonal bipyramidal structure with a linear NO in the equatorial plane and a facial etp ligand. The crystals are monoclinic, space group P21/n, with unit cell dimensions a = 14.130(2), b = 21.026 (3), c = 14.760 (1) Å, β = 97.88 (l)°V = 4344 Å3, Z = 4, R = 0.046 and Rw = 0.056 for the 4779 intensities with Fo2 > 3σ(Fo2) and the 440 variables.
