Dinitrosylbis(triphenylphosphine)ruthenium

Abstract

Ru(NO)2[P(C6Hs)3]z, monoclinic, P21/n, a= 9-96 (1), b=37.01 (2), c=9.31 (1)/~, fl=111.44 (3) °, Z = 4, Dx = 1.425, V= 3194/~3, F(000) = 662,/z(Mo K~) =5-28 cm -1. The structure has been refined by fullmatrix least-squares calculations to Rw = 0.0485 for 927 unique observed reflexions. There is a distorted tetrahedral coordination about ruthenium, with mean bond lengths and angles" Ru-P, 2.339 (7); Ru-N, 1.72 (3); N-O, 1.22 (2)/~; P-Ru-P, 105.5 (3); N-Ru-N, 139.9 (8) ° . Ru-N-O angles are 168.0 (1.6) and 174.7 (1.7) °. Apart from the conformation of the triphenylphosphine groups the molecular structure is similar to that found in crystals of Ru(NO)2[P(C6Hs)3]2 • ½C6H6.

A combined experimental and theoretical study of dinitrosyl iron complexes containing chelating bis(diphenyl)phosphinoX (X=benzene, propane and ethylene): X-ray crystal structures and properties influenced by the presence or absence of π-bonds in chelating ligands

“…xxi For example, the N-M-N and O-M-O bond angles reported for M(NO) 2 (PPh 3 ) 2 complex are 139.2° and 142.7° when M = Ru xxii and 139.1° and 140.6° when M = Os. xxiii This is also true for the cationic species, [M(NO) 2 (PPh 3 ) 2 ] + , where the reported N-M-N and O-M-O bond angles are 157.5° and 173.7° for Rh and 154.2° and 167.5° for Ir, respectively.…”

Oxygen-transfer reactions in platinum metal complexes of nitric oxide and sulphur dioxide

“…Reaction of [Ru(NO),(PPh,),] with SO2.-In [Ru(NO),-(PPh,),] the nitrosyl ligands are co-ordinated to the metal in a conventional linear fashion (Ru-N-0 = 168-178°). 21 We have studied the reaction of this 18electron complex with SO, because it provided an interesting comparison to that of the platinum dinitrogen with SO, occurs much more slowly than that with [Pt(N202)(PPh3),]. After leaving a solution of [Ru-(NO),(PPh,),] under an SO, atmosphere for several weeks a dark green (almost black) crystalline airsensitive solid separated from the solution.…”

Pas de Deux of an NO Couple: Synchronous Photoswitching from a Double‐Linear to a Double‐Bent Ru(NO)2 Core under Nitrosyl Charge Conservation

“…Structure analysis showed isotypy of the crystals with those analysed by Bhaduri and Sheldrick half a century ago. [13] Prior to their work, the Eisenberg and Ibers groups published the structure of the hemi-benzene adduct 1• 1 = 2 C 6 H 6 . [12] Figure 1 shows the result of our redetermination at a temperature of 100 K. 6), Ru1À P1 2.3367 (15), Ru1À P2 2.3415(15); N1À Ru1À N2 141.9(2), Ru1À N1À O1 169.9(5), Ru1À N2À O2 172.8(5), P1À Ru1À P2 104.87 (5).…”
