Universidad de Zaragoza (orcid)0000-0002-3284-1053 Unequivocal characterization of an osmium complex with a terminal sulfide ligand and its transformation into hydrosulfide and methylsulfide 2024 Access copy available to the general public Unrestricted Deprotonation of the thioamidate group of [OsH{κ2-N,S-[NHC(CH3)S]}(≡CPh)(IPr)(PiPr3)]OTf [1; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolylidene; OTf = CF3SO3] results in the release of acetonitrile and formation of the terminal sulfide complex OsH(S)(≡CPh)(IPr)(PiPr3) (2), which has been transformed into the hydrosulfide [OsH(SH)(≡CPh)(IPr)(PiPr3)]OTf (3) and the methylsulfide [OsH(SMe)(≡CPh)(IPr)(PiPr3)]OTf (4) through protonation and methylation reactions, respectively. The structure, spectroscopic characteristics, and reactivity of these compounds are compared. Reactions of 3 and 4 with 2-hydroxypyridine and 2-mercaptopyridine afford [OsH{κ2-X,N-[X-py]}(≡CPh)(IPr)(PiPr3)]OTf [X = O (5), S(6)]. info:eu-repo/grantAgreement/ES/DGA/E06-23R info:eu-repo/grantAgreement/ES/MICINN-AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MICINN/PID2020-115286GB-I00/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MICINN/RED2022-134287-T info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.7 2024 CHEMISTRY, INORGANIC & NUCLEAR 6 / 43 = 0.14 2024 Q1 T1 0.958 2024 Chemistry (miscellaneous) 2024 Q1 Physical and Theoretical Chemistry 2024 Q1 Inorganic Chemistry 2024 Q1 7.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Esteruelas, Miguel A.
