“…As a result, the syntheses and structural studies of well‐defined Ru–Sn complexes are of current interest. Despite the well‐established insertion reaction of tin dichloride into metal–halogen bonds, the reaction of SnCl 2 with ruthenium derivatives has been scarcely observed . 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.…”

A set of neutral and ionic ruthenium arene trichlorostannyl complexes are reported herein. The tin(II) compounds L 1 SnCl {1; L 1 = [2-(CH 2 NEt 2 )-4,6-(tBu) 2 C 6 H 2 ] -} and [L 2 SnCl][SnCl 3 ] {2; L 2 = 2,6-[(CH 3 )C=N(C 6 H 3 -2,6-iPr 2 ) 2 ]C 5 H 3 N} showed a rather different reactivity towards the ruthenium complex [(η 6cymene)RuCl] 2 (η-Cl) 2 . As a consequence, the neutral complex [Ru(η 6 -cymene)(L 1 SnCl)Cl 2 ] (4) and the ionic compound [L 2 SnCl][Ru(η 6 -cymene)(SnCl 3 ) 2 Cl] (8) were isolated. The insertion reaction of 4 with SnCl 2 provided the neutral trimetallic ruthenium complex [Ru(η 6 -cymene)(L 1 SnCl)(SnCl 3 )Cl] (6). Analo- [a]

“…The use of NaBH 4 as a reagent to prepare tin trihydride complexes turns out to be an interesting synthetic method in tin chemistry that we had previously used to synthesise several [M]–SnH 3 derivatives ,,,,,,. In the present study, this route allowed the preparation of the first iridium complexes containing tin trihydride as a ligand.…”

Mono‐ and bis(trichlorostannyl) complexes [MCl(SnCl3)(η5‐C5Me5){P(OR)3}] (1, 2) and [M(SnCl3)2(η5‐C5Me5){P(OR)3}] (3, 4) (M = Rh, Ir; R = Me, Et) were prepared by allowing chloro compounds MCl2(η5‐C5Me5)[P(OR)3] to react with anhydrous SnCl2 in refluxing 1,2‐dichloroethane. Treatment of trichlorostannyl complexes of iridium 2 and 4 with NaBH4 in ethanol afforded hydride‐trihydridestannyl derivatives [IrH(SnH3)(η5‐C5Me5){P(OR)3}] (5) and bis(trihydridestannyl) [Ir(SnH3)2(η5‐C5Me5){P(OR)3}] (6), the reaction of which with methylpropiolate HC≡CCOOMe led to trivinylstannyl derivatives [IrH{Sn[C(COOMe)=CH2]3}(η5‐C5Me5){P(OMe)3}] (7 a) and [Ir{Sn[CH=C(H)COOMe]3}2(η5‐C5Me5){P(OMe)3}] (8 a). The complexes were characterised spectroscopically (IR and 1H, 31P, 13C, 119Sn NMR) and by X‐ray crystal structure determination of [Ir(SnCl3)2(η5‐C5Me5){P(OMe)3}] (4 a).

“…Infrared and 13 C{ 1 H} NMR spectra attest also the presence of formates by showing two bands at 1674-1594 cm −1 (ν OCO , asym) and one resonance at δ 166 ppm [OC(O)H], respectively (Table 4). In 2008, the same group reported a similar structure by standing the ruthenium-cyclopentadienyl-trihydridostannyl complex, Ru(SnH3)(Cp)[P(OEt)3](PPh3), under a CO2 atmosphere for 5 h (Scheme 18) [64]. The resulting formate species was characterized as [Ru[Sn{OC(O)H}2(μ-OH)](Cp){P(OEt)3}(PPh3)]2 (10), exhibiting a structure based on two μ-OH groups bridging the tin atoms ( Figure 13).…”

Single-crystal X-ray diffraction structures of organotin compounds bearing hemicarbonate and carbonate ligands were recently reviewed by us—“CO2 Derivatives of Molecular Tin Compounds. Part 1: Hemicarbonato and Carbonato Complexes”, Inorganics2020, 8, 31—based on crystallographic data available from the Cambridge Structural Database. Interestingly, this first collection revealed that most of the compounds listed were isolated in the context of studies devoted to the reactivity of tin precursors towards carbon dioxide, at atmospheric pressure or under pressure, thus highlighting the suitable disposition of Sn to fix CO2. In the frame of a second part, the present review carries on to explore CO2 derivatives of molecular tin compounds by describing successively the complexes with carbamato, formato, and phosphinoformato ligands, and obtained from insertion reactions of carbon dioxide into Sn–X bonds (X = N, H, P, respectively). The last chapter is devoted to X-ray structures of transition metal/tin CO2 complexes exhibiting metallocarboxylato ligands. As in Part 1, for each tin compound reported and when described in the original study, the structural descriptions are supplemented by synthetic conditions and spectroscopic data.
