The Synthesis of a Novel Cyclo-Se3-Bridged Trinuclear Ru Complex

Novel Polyselenidoarsenate and Selenidoarsenate: Solvothermal Synthesis and Characterization of [Co(phen)3][As2Se2(μ-Se3)(μ-Se5)] and [Co(phen)3]2[As8Se14]

“…[5][6][7] However, the Se-As-Se angles scatter in a wider range compared to the angles of the cyclic anion 22 The [As 2 Se 2 (μ-Se 3 )(μ-Se 5 ) 2-] ¥ polymeric anion contains μ-Se 3 and μ-Se 5 bridging ligands. As a common structural unit of polyselenides, the triselenide unit Se 3 2has been observed as a terminal, 23 a μ-Se 3 , 21 or a μ-cyclo-Se 3 24 brigding ligand in transition-metal polyselenides. However, the bidentate bridging μ-Se 5 coordination mode is rare for the pentaselenide Se 5 2unit.…”

Novel C–H activation and C–S formation reactions on disulfide and diselenide ligands in dinuclear ruthenium complexes

“…The contribution from (iii) was shown to be negligible through spectroscopy studies [41][42][43][44][45][46]. Since our first report of the disulfide-bridged Ru III dinuclear complex, [{Ru(P(OCH 3 ) 3 ) 2 Cl} 2 (l-S 2 )(l-Cl) 2 ] (1) [53], we have developed various C-H cleavage and C-S formation reactions of unsaturated organic molecules on the disulfide ligand [54][55][56][57][58][59][60][61][62][63]. The selenium analogue, [{Ru(P(OCH 3 ) 3 ) 2 Cl} 2 (l-Se 2 )(l-Cl) 2 ] (2), has also been synthesized and similar reactions were performed [64].…”

17 The noble metals

“…27 The reaction of [{RuCl[P(OMe) 3 ] 2 } 2 (m-Cl) 2 (m-Se 2 )] with NaPF 6 in MeCN gave as one of the products [{Ru(NCMe)[P(OMe) 3 ] 2 }(m-Cl)(m-Se 3 )-{Ru(NCMe) 3 [P(OMe) 3 ] 2 } 2 ] 41 , with a new cyclic neutral Se 3 ligand. 28 The affinity of Ru complexes towards NO prompted a search for a complex to act as an NO scavenger in medical use. The criteria of fast reaction, stability, low toxicity and rapid clearance led to the study of [Ru(Hedta)(OH) 2 ] and [Ru(H 3 dtpa)Cl] and these were found to have suitable behaviour.…”
