Kristallstruktur, Schwingungsspektren und Normalkoordinatenanalyse von (CH2py2)[Ru(NO)FCl4]

Abstract: Bei der Umsetzung von [Ru(NO)Cl5]2– mit an BrF3 gesättigter Frigen‐Lösung in Dichlormethan entsteht der Komplex [Ru(NO)FCl4]2–, der durch Ionenaustauschchromatographie an Diethylaminoethyl‐Cellulose von Hydrolyseprodukten getrennt werden kann. Die Röntgenstrukturanalyse an einem Einkristall von (CH2py2)[Ru(NO)FCl4] · 1/2 (CH3)2CO (triklin, Raumgruppe P1, a = 9,416(2), b = 14,919(6), c = 15,127(3) Å, α = 61,86(3), β = 80,31(2), γ = 72,49(3)°, Z = 4) zeigt, daß das Fluoratom trans‐ständig zur Nitrosyl‐Gruppe ang… Show more

“…Two bands at 644 and 607 cm –1 are assigned to the ν(TcN) stretching vibration and the δ(TcN) bending mode. These values are in agreement with the values found for Na 2 [Ru(NO)F 5 ] and (CH 2 py 2 )[Ru(NO)FCl 4 ] , . The bands of the NO stretching vibration show a weak splitting in the IR and Raman spectra of Cs 2 [Tc(NO)F 5 ] (1772 and 1764 cm –1 ).…”

“…Ru (2) atoms are displaced from the rms planes defined by the equatorial atoms towards the nitroso group by 0.18 Å and 0.14 Å respectively. The cis bond angles at the Ru atom deviate from 90° by 0.9-8.5°.…”

“…At most, potassium or ammonium salts of the nitrosopentachlororuthenate anion are used in the syntheses [1][2][3][4][5], these salts being readily available with good yields from ruthenium thrichloride [6]. However, these salts are insoluble in organic solvents and when reactions are carried out in non-aqueous media, the starting ruthenium compound is the nitrosotrichloro complex RuNOCl 3 nH 2 O [7][8][9][10][11][12].…”

“…Die Ru±Cl-Bindung ist mit 2,347 A Ê um 1±2% ku È rzer als in anderen bekannten Chloronitrosylruthenaten [2,4,11]. Sterische Wechselwirkungen, die bei (CH 2 py 2 )[Ru(NO)ClBr 4 ] und (CH 2 py 2 )[Ru(NO)-FCl 4 ] diskutiert worden sind [2,3], haben kaum Einfluû auf die Bindungsla È ngen. Alle Cl±Ru±I-Winkel sind geringfu È gig kleiner als 90°.…”

“…Ku È rzlich haben wir u È ber die Darstellung halogengemischter Komplexe [Ru(NO)Cl n Br 5-n ] 2± , n = 0±5 und [Ru(NO)FCl 4 ] 2± berichtet. An (CH 2 py 2 )[Ru(NO)ClBr 4 ] und (CH 2 py 2 ) [Ru(NO)FCl 4 ] sind die Kristallstrukturen bestimmt worden [2,3]. Von den dimeren Halogenonitrosylruthenaten ist nur [{Ru(NO)Cl 3 } 2 (l-Cl 2 )] 2± bekannt [4].…”
