Samenvatting

A set of neutral and ionic ruthenium arene trichlorostannyl complexes are reported herein. The tin(II) compounds L 1SnCl {1; L 1 = [2-(CH 2NEt 2)-4,6-(tBu) 2C 6H 2] } and [L 2SnCl][SnCl 3] {2; L 2 = 2,6-[(CH 3)C=N(C 6H 3-2,6-iPr 2) 2]C 5H 3N} showed a rather different reactivity towards the ruthenium complex [(η 6-cymene)RuCl] 2(η-Cl) 2. As a consequence, the neutral complex [Ru(η 6-cymene)(L 1SnCl)Cl 2] (4) and the ionic compound [L 2SnCl][Ru(η 6-cymene)(SnCl 3) 2Cl] (8) were isolated. The insertion reaction of 4 with SnCl 2 provided the neutral trimetallic ruthenium complex [Ru(η 6-cymene)(L 1SnCl)(SnCl 3)Cl] (6). Analogous ruthenium complexes [Ru(η 6-cymene)(L 3PPh 2)Cl 2] (5) and [Ru(η 6-cymene)(L 3PPh 2)(SnCl 3)Cl] (7) containing the phosphane ligand L 3PPh 2 {3; L 3 = [2,6-iPr 2-(C 6H 3)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 [SnCl 3] 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.
