Abstract
Chelating triphosphines were applied to freeze the fluxionality and to minimize the number of isomers found in the monophosphine analogues and this technique was proved to be useful. RuH(NO)P3(P3; Cyttp, ttp and etp) complexes were characterized to have similar trigonal bipyramidal structures with linear NO groups. Cyttp prefers to have a meridional geometry while etp prefers a facial one and ttp complexes are mixture of these two isomers. The crystal structure of RuH(NO)(Cyttp) has been determined to have a distorted trigonal bipyramidal structure with a linear NO in the equatorial plane. The crystals are orthorhombic, space group Pnma, with unit cell dimensions a = 16.356(2), b = 20.474(2), c = 10.915(l) Å, V = 3655 Å3, Z = 4, R = 0.035 and Rw = 0.034 for the 2900 intensities with Fo2 > 3σ(Fo2) and the 208 variables.
