Preparation of mono- and bis-(hydrazine) complexes of ruthenium(II) †
Journal of the Chemical Society, Dalton Transactions, 1997Hydrazine complexes [RuH(R1NHNH2)L4]BPh4 1–3, [Ru(R1NHNH2)2L4][BPh4]2 4–6 [R1 = H, Me, Ph, 4-MeC6H4 or 4-O2NC6H4; L = P(OEt)3, PPh(OEt)2 or P(OMe)3] were prepared by allowing the hydride species [RuH2L4] to react, first with triflic acid (CF3SO3H) and then with an excess of the appropriate hydrazine. The derivatives [RuH(Me2NNH2){P(OEt)3}4]BPh4 1f, [Ru(

Abstract X-ray crystal structure analysis of [Ru(η 2 -CS 2 Me)(CO) 2 (PPh 3 ) 2 ]ClO 4 reveals that the dithioester function is co-ordinated through carbon and the un-methylated sulphur atom; the chelate ring is opened by introduction of bidentate diethyldithiocarbamate and the resulting monodentate dithioester reacts rapidly with acids producing ...

Mono- and dinuclear ruthenium(ii) 1,6,7,12-tetraazaperylene complexes
Dalton Transactions, 2012We report the synthesis of free 1,6,7,12-tetraazaperylene (tape). Tape was obtained from 1,1'-bis-2,7-naphthyridine by potassium promoted cyclization followed by oxidation with air. Mono- and dinuclear ruthenium(II) 1,6,7,12-tetraazaperylene complexes of the general formulas [Ru(L-L)(2)(tape)](PF(6))(2), [1](PF(6))(2)-[5](PF(6))(2), and [{Ru(L-L)(2)}(2)

The complex [RuCl2(PPh3)3] or [RuCl(H)(dma)(PPh3)2](dma = MeCONMe2) reacts with 2 mol of PF3 to give cis-[RuCl2(PF3)2(PPh3)2]. The analogous complex cis-[RuCl2{PF2(NMe2)}2(PPh3)2] made from either [RuCl2-(PPh3)3] or [{RuCl2(OCMe2)(PPh3)2}2]. undergoes ready dissociation of PPh3 in solution to give [RuCl2{PF2-(NMe2)}2(PPh3)].

Disulphidothionitrate nitrosyl complexes of ruthenium(II)
Inorganica Chimica Acta, 1987Abstract The complexes Ru(NO)X3L2 (X = Cl or Br; L = PPh3 or AsPh3) react with heptasulfurimide (S7NH) in dimethylformamide to afford disulphidothionitrate (S3N−) complexes Ru(NO)(S3N)X2L. The reactions of Ru(NO)X3·2H2O (X = Cl, I) with S7NH in methanol produce six coordinated {RuNO}6 complexes Ru(NO)(S3N)2X.
