Tellurated heterocycles, 2-[(2-thienyltelluro)methyl]tetrahydrofuran (L1) and [(2-thienyltelluro)methyl]tetrahydro-2H-pyran (L2): Synthesis and complexation reactions with Pd(II), Pt(II), Hg(II), Ru(II) and Cu(I)

“Piano‐Stool” Complexes of Ruthenium(II) Designed with Arenes and N‐[2‐(Arylchalcogeno)ethyl]morpholines: Highly Active Catalysts for the Oxidation of Alcohols with N‐Methylmorpholine N‐Oxide, tert‐Butyl Hydroperoxide and Sodium Periodate and Oxychloride

“…For the cation of 4 , the Ru–Cl bond length [2.413(3) Å] is consistent with those of 1 and 3 . The Ru–Cl bond length of the cation of 6 [2.4078(14) Å] is consistent with those in earlier reports of 2.415(2)/2.422(2) Å for dichloro(η 6 ‐ p ‐cymene){bis[2‐(2‐thienyl)ethyl] telluride}ruthenium(II)39 and 2.417(2)–2.436(2) Å for [RuCl 2 (η 6 ‐ p ‐cymene)L] (L = monodentate Te ligand)44–46 and [RuCl{η 2 ‐C,N‐C 6 H 3 (CH 2 NMe 2 ) 2 ‐2,6}{η 6 ‐C 10 H 14 }] 47. It is somewhat longer than the value 2.308(2) Å reported for[(η 6 ‐ p ‐cymene)RuCl(H 2 NCH 2 CH 2 TeC 6 H 4 OMe)]Cl · H 2 O,38but the difference with the values for 1 , 3 , and 4 are not very significant.…”

Palladium and half sandwich ruthenium(II) complexes of selenated and tellurated benzotriazoles: Synthesis, structural aspects and catalytic applications

“…However, Ru-Cl bond distance of the cation of 4 is somewhat longer than 2.308 (2) [46]. The Ru-C bond distances 2.170(10)À2.231(10) Å and C-Ru-C bond angles of the cation of 4 are consistent with earlier reports on species having Ru(p-cymene) unit [52][53][54][55][56][57][58]. The bond angles at the coordinating Te and N atoms are as expected for nearly trigonal-pyramidal and tetrahedral geometries, respectively.…”

“…The Ru-N bond length (2.085(7) Å) is consistent with the sum of covalent radii ca. (19) Å for Ru(II)(g 6 -benzene)-complexes of bis(pyrazol-1-yl)pyridazine and Ru(II)(g 6 -p-cymene)-complexes of 3,6-bis(3,5-dimethylpyrazol-1-yl)pyridazine [48] [RuCl 2 (p-cymene)L] (L = monodentate Te-ligand) [56][57][58] and [RuCl{g 2 -C,N-C 6 H 3 (CH 2 NMe 2 ) 2 -2,6}{g 6 -C 10 H 14 }] [59]. However, Ru-Cl bond distance of the cation of 4 is somewhat longer than 2.308 (2) [46].…”

Unprecedented oxidation of half-sandwiched ruthenium(II) in the excess of ammonium hexafluorophosphate and formation of nanosized Ru–RuS2

“…An extensive chemistry of such compounds is known [3]. Numerous half-sandwich complexes of (h 6 -arene)Ru(II) unit with hybrid organochalcogen ligands (having N and/or O as other donor atoms) behaving as monodentate [4,5], bidentate [6e9] and tridentate [10e13], have been reported in last decade. Half-sandwich complexes of Ru(III) are generally formed by (h 5 -Cp/Cp*)Ru(III) unit and most of them are binuclear.…”
