Bimetallic ruthenium–tin chemistry: Synthesis and molecular structure of arene ruthenium complexes containing trichlorostannyl ligands

Anticancer activity of new organo-ruthenium, rhodium and iridium complexes containing the 2-(pyridine-2-yl)thiazole N,N-chelating ligand

“…In 7 the Ru-Sn bond length is comparable to those found in other mononuclear arene ruthenium trichlorostannyl complexes [15].…”

“…In the mass spectra of 6 and 7 molecular ion peaks are not observed, but fragments that correspond to the loss of SnCl 3 . However, the 119 Sn NMR spectra of 6 and 7 contain a peak at d = -364.47 for 6 and d = -265.26 ppm for 7, indicative of the coordinated SnCl 3 unit [15]. Moreover, the [7]PF 6 crystallises in the orthorhombic space group Pnma.…”

Role of the Trichlorostannyl Ligand in Tin–Ruthenium Arene Complexes: Experimental and Computational Studies

“…As an example, the cyclopentadienyl ruthenium trichlorostannyl complexes [(η 5 ‐C 5 H 5 )(phosphane) 2 Ru(SnCl 3 )] have been synthesized and tested as catalysts for the preparation of methyl acetate from methanol, the selective electrochemical oxidation of methanol to dimethoxymethane,[5e] carbene–carbene coupling reactions,[5f] and the methylation of alkylamines. [5g] In addition to the cyclopentadienyl ruthenium trichlorostannyl complexes, a few arene ruthenium complexes containing trichlorostannyl ligands have also been reported (Figure A) …”

Synthesis and In Vitro (Anticancer) Evaluation of η6-Arene Ruthenium Complexes Bearing Stannyl Ligands

“…The reaction of half-sandwich ruthenium(II) arene complexes [(η 6 -C 6 H 6 )RuCl 2 (PR 3 )] (R = aryl or O-Aryl, O-alkyl) with SnCl 2 is also known to yield a Ru(II) complex exhibiting a strong covalent Ru-Sn bond via facile insertion of the SnCl 2 moiety into the Ru-Cl bond [35,36]. While the reaction of SnX 2 (X = halide) with other metals, such as palladium and platinum, has been extensively studied [37,38], the analogous reaction with ruthenium derivatives has received far less attention.…”

“…All starting materials and solvents were obtained commercially (Strem, Sigma-Aldrich, Zwijndrecht, Netherlands) and used as received. [(η 6 -C 6 H 6 )RuCl 2 (PPh 3 )], [(η 6 -C 6 H 6 )RuCl 2 (P(OPh) 3 )], and [(η 6 -C 6 H 6 )RuCl(SnCl 3 )(PPh 3 )] were prepared according to published procedures [31][32][33][34][35][36], and the complexes obtained were characterised by 1 H and 31 P NMR spectroscopy and checked against literature data. NMR spectra were recorded on a Bruker Ultrashield 300 (Karlsruhe, Germany), IR spectra on a Shimadzu MIRacle IR (ATR, Kyoto, Japan), UV-vis on a Shimadzu UV 3600 (Kyoto, Japan), and TGA spectra were recorded on a TGA Q-500 (Maastricht, Netherlands) at the University of Maastricht Brightlands Campus, Netherlands.…”
