Thionitrosylkomplexe des Osmiums. Die Kristallstruktur von AsPh4[OsCl4(NS)2Cl]

Abstract: Osmiumpentachlorid reagiert mit Trithiazylchlorid, (NSCl)3, unter Bildung des Thiazylchloridkomplexes [OsCl4(NSCl)2], aus dem mit Tetraphenylarsoniumchlorid in Dichlormethanlösung der Thionitrosyl‐Komplex AsPh4[OsCl4(NS)2Cl] entsteht. Mit Galliumtrichlorid läßt sich hieraus der ungeladene Thionitrosylkomplex [OsCl4(NS)2] herstellen. Die IR‐Spektren der neuen Komplexe werden mitgeteilt und zugeordnet. Die Kristallstruktur von AsPh4[OsCl4(NS)2Cl] wurde mit Hilfe von Röntgenbeugungsdaten ermittelt und bis zu eine… Show more

“…The multiple bond character of the Os−N bond is in agreement with the short Os−N bond distances. The N−S bond lengths of 1.489(15) and 1.493(8) Å for 3c and 4 and are comparable to bond distances in other thionitrosyl complexes. 5e,, The N−S bond lengths are also consistent with largely NS + character by comparison with the NS + cation in which the N−S bond length is 1.495 Å . The Os−N−S bond angle is almost linear at 179.3(9)° in [Os II (tpm)(Cl) 2 (NS)] + and at 166.9(9)° in Os II (Tp)(Cl) 2 (NS).…”

“…Low-intensity bands for 3b and 4 appear in the region 540−420 cm -1 which shift ∼15 cm -1 in 15 N-labeled complexes. A related series of bands appear at 495, 454, and 221 cm -1 for [Os(NS)(NSCl)(Cl) 4 ] - which have been assigned to the normal modes ν s (Os−N), ν as (Os−N), and δ(Os−NS) …”

“…Consequently, reports of structurally characterized early transition metal thionitrosyl complexes are rare compared to thionitrosyl complexes featuring 4d and 5d late transition metals. 2,[9][10][11][12][13][14][15][16][17] We sought to isolate such species directly from a vanadium nitride and elemental sulfur and chose the vanadium nitride [(nacnac)VRN(OAr)] 18 (nacnac À = [ArNC(CH 3 )] 2 CH, Ar = 2,6-i Pr 2 C 6 H 3 ), since the metal is in a lowcoordinate environment, and the nitride ligand that is formally in a V (V) RN (3À) should be charge-polarized enough to act as a strong nucleophile attacking sulfur. In this work we describe the first vanadium thionitrosyl, which is characterized by a wide array of spectroscopic methods (including the 15 N enriched isotopologue), and single crystal X-ray diffraction studies.…”
