Technetium(V) and rhenium(V) nitrido complexes with bis(diphenyl-thiophosphoryl)amide, N(SPPh2)2−

Ruthenium chalcogenonitrosyl and bridged nitrido complexes containing chelating sulfur and oxygen ligands

“…While nitrosyl complexes of transition metals are well documented, 1 the chemistry of the heavier chalcogen analogues, namely, thionitrosyl and selenonitrosyl complexes, has received less attention [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] due, in part, to the difficulty of their preparations. Common synthetic routes to thionitrosyl complexes include (a) sulfur atom transfer to metal nitrides, (b) reaction of N 3 S 3 Cl 3 or NS + salts with metal complexes, (c) halide abstraction from thiazyl complexes, and (d) reaction of S 4 N 4 with metal halides or nitrides.…”

Reactivity of Binary and Ternary Sulfur Halides towards Transition‐Metal Compounds

“…Treatment of the technetium compounds [TcN(morphtcb) 2 ] [ 17 , morphtcb= N ‐( N′′ ‐morpholinyl‐thiocarbonyl)benzamidinato)] as well as [TcN{N(SPPh 2 ) 2 }(PMe 2 Ph) 2 ] ( 18 ) with S 2 Cl 2 did not furnish technetium(III) compounds, but formed complexes in the oxidation state +II (Scheme ), as supported by EPR spectroscopy …”

“…The reaction of S 2 Cl 2 with transition‐metal nitrides 13 a – 13 d can further be extended to phosphine, arsine, dithiocarbamato, thiocarbamoylbenzamidinato, thiophosphorylamide, (bi)pyridine, phenanthroline nitride compounds of technetium(V), rhenium(V), and osmium(VI). In the reactions of [Re(A)(Cl) 2 (N)(PMe 2 Ph) 2 ] [A = N(SPPh 2 ) 2 ( 15 a ), N ‐( N , N ‐dialkylthiocarbamoylbenzamidinate) ( 15 b ), diethyldithiocarbamate ( 15 c )] with S 2 Cl 2 , Abram and co‐workers observed ligand dissociation yielding 11 a along with 12 a and [Re(N)(A) 2 ] ( 16 a – 16 c ) (Scheme ) . Separation of the phosphine complexes was achieved by fractional crystallization.…”

N-Imidazole–boron trichloride adduct

“…1, and selected bond lengths and angles are presented in Table 1. A variety of nitrogen adducts of BCl 3 have previously been characterized crystallographically. These include amine Minkwitz, Nass, Rieland & Preest, 1987;Avent et al, 1995, Hess, 1969Anton et al, 1984;Abram et al, 1997;Voigt et al, 2000), pyridine (Tö pel et al, 1981) and acetonitrile (Swanson et al, 1969) adducts. The B-N bond length in (I) is shorter than any previously reported, with the exception of adducts with rhenium nitride complexes (Dantona et al, 1984;Abram et al, 1997;Ritter & Abram, 1996).…”
