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 [LCN(n-Bu)SnCl]-Sn-[Sn(n-Bu)LCN]2(μ-Cl)} (10) and LCN(n-Bu)2SnCl. 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
