dcterms:description
The L(CN)n-BuSnCl2 where L-CN is 2-(N,N-dimethylaminomethyl)phenyl-as a chelating ligand was reduced by one molar equivalent of potassium to distannane L(CN)n-Bu(Cl)Sn-Sn(Cl)n-BuLCN (3). The same reduction of (L2SnCl2)-Sn-CN led essentially quantitatively to the stannylene (L2Sn)-Sn-CN. Distannane 3 can be oxidized to corresponding organotin(IV) chalcogenides (L(CN)n-Bu(Cl) Sn-Y-Sn(Cl)n-BuLCN, where Y is O, S, Se, and Te). The structure of these chalcogenides was evaluated by multinuclear NMR spectroscopy techniques and X-ray crystallographic techniques for sulfide, revealing two diastereomeric pairs with the centre of chirality at the tin atoms for all compounds. The further reduction of 1 by excess of reducing agents gave tetranuclear compound [L-CN(n-Bu)SnCl]-Sn-{[Sn(n-Bu)L-CN](2)(mu-Cl)} (10) and L-CN(n-Bu)(2)SnCl. The product of reduction of 3 by K(BEt3)H.THF is the complex 10 as well. The structure and bonding properties in 10 were conducted at DFT theory level.
