Crystal and molecular structures of the binuclear complex of rhodium(III) chloride with selenium dichloride and the complex of iridium(III) chloride with sulfur dichloride and tetrachloride

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

“…The structure reveals interactions of the sulfur atom and the chlorine atoms of the anion. Similar interactions were found in [(SCl 3 ) 2 ][OsCl 6 ] ( 106 d ), [SCl 3 ][RuCl 3 (SCl 2 ) 2 ] ( 107 ), and [SCl 3 ][IrCl 4 (SCl 2 ) 2 ] ( 108 ) and the chlorine atoms of the two anions in [SCl 3 ][Ti 2 Cl 9 ] ( 109 ) . Thermal decomposition of [SCl 3 ][AuCl 4 ] ( 3 ) revealed a stepwise degradation which is initiated by the loss of a chlorine molecule at 133 °C to yield [AuCl 3 (SCl 2 )] ( 4 ) (see section 2.1 ) followed by SCl 2 release at 151 °C and the precipitation of AuCl 3 which can be further decomposed to elemental gold by heating the sample up to 333 °C .…”

Bridging Nonaselenium Ring in [Se9(IrBr3)2], and Three Modifications of the Mononuclear Complex [IrBr3(SeBr2)3]

“…mononuclear iridium complexes with only terminal selenium and halogen ligands, are still missing. Yet, mononuclear chalcogen halides of platinum-metals are known, for example, the square-planar PdX 2 (SeX 2 ) 2 (X = Cl, Br), [4,5] as well as octahedral complexes, such as MCl 4 (SCl 2 ) 2 (M = Pd, Pt), [6] RhCl 3 (SCl 2 ) 3 , [7] SCl 3 [RuCl 3 (SCl 2 ) 3 ], [8] SCl 3 [IrCl 4 (SCl 2 ) 2 ], [9] and (YX 3 ) 2 [MX 6 ] (M = Os, Ir; X = Cl, Br; Y = S, Se, Te). [10] Herein we present the syntheses and crystal structures of three different modifications of the mononuclear iridium complex [IrBr 3 (SeBr 2 ) 3 ].…”

Osmium thioselenochloride Os2S6Se2Cl8: Synthesis, cluster isolation, and structure

“…Their compositions and structures depend on the con ditions of the synthesis and the chlorine to chalcogen ratio in the reaction mixture. While the documented ternary osmium complexes with sulfur (selenium) and chlorine are few (OsS 2 Cl 12 and OsSe 2 Cl 12 [1] as the cation-anion complexes [OsCl 6 ] 2--2[:ChalCl 3 ] + ; OsS 4 Cl 2 [2] with an unclear structure), the number of quaternary complexes of the system Os-S-Se-Cl is substantially higher. For instance, the complex Os 4 S 11 SeCl 8 [3] is known to exist as the 1D polymer [Os 2 Cl 4 (μ S 2 )(μ S(S,Se)) 2 ] n , which is simultaneously a cluster containing a metal-metal bond and a molec ular complex with polychalcogenide groups.…”
