Linked triosmium cluster complexes containing thiolato-carboxylato ligands: the crystal and molecular structures of [{Os3H(CO)10}2(μ-SC6H4CO2)] and [{Os3H(CO)10}2(μ-SCH2CH2CO2)]

Synthesis and Characterization of Thiolate‐Oxo Ligated Zinc Alkyl Derivatives for Production of Zn‐Based Nanoparticles

“…The metrical data of 1 - 3 were found to be consistent with those reported in the literature. [33-36, 38, 39, 43-48] Select angles and bond distances are given in Table 1.…”

“…Several crystal structures with the 3MPA bound to a transition metal have been previously reported. [37-39, 41, 42, 61] In this set of compounds, the 3MPA was found to act as a terminal ligand binding through the thiolate [41] or through the oxide [61] , chelating through a single oxygen and thiolate [37, 42] , or bridging as noted for (C 5 Me 4 Et) 2 Zr[(μ-O 2 C(CH 2 ) 2 S)Au(P(C 6 H 5 )(CH 3 ) 2 ] 2 [38] or [(CO) 9 Os 3 ] 2 (μ-3MPA) [39] . As can be discerned, the polymeric nature that the 3MPA ligand displays in 1 has not been previously reported.…”

Group VIII Metal Carbonyl Cluster-Boronic Acid Conjugates: Cytotoxicity and Mode of Action Studies

“…As we envisaged that the boronic acid functionality of 2 may undergo oxidation to form the hydroxyl group in vivo, the analogue 2-OH was also synthesized and its structure confirmed crystallographically (Figure S2a). − The ruthenium homologue of 2 , viz., 2′ , was similarly synthesized from the reaction of Ru 3 (CO) 10 (NCCH 3 ) 2 ( 1′ ) with 4-mercaptophenylboronic acid ( BA ). The iron homologue of 2 is not accessible from the reaction of the monothiol with iron carbonyls; they tend to lead to diiron dithiolato carbonyl compounds .…”

Reactivity of 2-(Diphenylphosphanyl)thiophenol (HSC6H4PPh2) with Ruthenium and Osmium Carbonyl Complexes; Breaking of HSC6H4PPh2 into Sulfide, Phenyl and Diphenylphosphanyl Ligands on a Triruthenium Cluster

“…[11] However, the reaction of 2-aminothiophenol with [Os 3 (CO) 10 (MeCN) 2 ] gives [Os 3 (µ-H)(µ-SC 6 H 4 NH 2 )-(CO) 10 ], [12] in which the NH 2 group is not coordinated. It is also known that [Os 3 (CO) 10 (MeCN) 2 ] reacts with 2-mercaptobenzoic acid to give the hexanuclear compound [{Os 3 (µ-H)(CO) 10 } 2 (µ-η 3 -SC 6 H 4 CO 2 )], [13] in which the SC 6 H 4 CO 2 ligand connects two triangles of osmium atoms through the thiolate and the carboxylate groups, each group bridging one edge of the corresponding trimetal fragment.…”

“…[9] Both [Ru 3 (CO) 12 ] and [Os 3 (CO) 12 ] react with thiophenol to give [M 3 (µ-H)(µ-SPh)(CO) 10 ] (M ϭ Ru, [2] Os [3] ) as primary products. However, these compounds undergo facile CϪS bond activation reactions, under thermal and/or photochemical conditions, leading to the sulfide derivatives [M 3 (µ 3 -S)(µ 3 -CO)(CO) 9 ] (M ϭ Ru, [2] Os [4] [5] ), [Os 3 (µ 3 -S) 2 (CO) 9 ], [3b,4,6] [M 3 (µ-H) 2 (µ 3 -S)(CO) 9 ] (M ϭ Ru, [2] Os [4] ), [Ru 4 (µ 4 -S)(µ-CO) 2 (CO) 9 ] [2] [Os 4 (µ 3 -S) 2 (CO) 13 ], [3b] [Os 4 (µ 3 -S) 2 (CO) 12 ], [3b] and [Os 6 (µ 4 -S) 2 (CO) 17 ]. [5] It has also been reported that [Os 3 (CO) 11 (MeCN)] reacts with m-and p-thiocresol to give [Os 3 (µ-H)(µ-SC 6 H 4 Me)(CO) 10 ] and that this reaction proceeds via the intermediate [Os 3 -(CO) 11 (HSC 6 H 4 Me)], in which both the sulfur and the hydrogen atoms of the thiol group interact with an osmium atom.…”
