eng Role of the Trichlorostannyl Ligand in Tin-Ruthenium Arene Complexes: Experimental and Computational Studies A set of neutral and ionic ruthenium arene trichlorostannyl complexes are reported herein. The tin(II)compounds (LSnCl)-Sn-1 {1; L-1 = [2-(CH2NEt2)-4,6-(tBu)(2)C6H2]-} and [(LSnCl)-Sn-2][SnCl3] {2; L-2 = 2,6-[(CH3)C=N(C6H3-2,6-iPr(2))(2)] C5H3N} showed a rather different reactivity towards the ruthenium complex [(eta(6-)cymene)RuCl](2)(eta-Cl)(2). As a consequence, the neutral complex [Ru(eta(6)-cymene)((LSnCl)-Sn-1)Cl-2] (4)and the ionic compound [(LSnCl)-Sn-2][Ru(eta(6)-cymene)(SnCl3)(2)Cl] (8)were isolated. The insertion reaction of 4 with SnCl2 provided the neutral trimetallic ruthenium complex [Ru(eta(6)-cymene)((LSnCl)-Sn-1)(SnCl3)Cl] (6). Analo-gous ruthenium complexes [Ru(eta(6)-cymene)((LPPh2)-P-3)Cl-2] (5)and [Ru(eta 6-cymene)((LPPh2)-P-3)(SnCl3)Cl] (7)containing the phosphane ligand L3PPh2 {3; L-3 = [2,6-iPr(2)-(C6H3)NH](-)} were also prepared to evaluate the donor-acceptor strength of the tin(II)-and phosphorus-containing ligands. The structural characterization and DFT calculations of the above-mentioned complexes suggest a strong influence of the [SnCl3](-)moiety on the Ru-E interaction (E = Sn, P). The influence of the trichlorostannyl ligand on the Ru-E interaction in the complexes 4-7 was further evaluated by means of a distortion/ interaction analysis. correlated molecular calculations; ray crystal-structure; gaussian-basis sets; pt-cl bonds; selective hydrogenation; phosphite ligands; sncl2 insertion; catalysts; reactivity; methanol
