Synthesis, characterization, and crystal structure of tetranuclear tin complex prepared from dimethyltin dichloride

Abstract

A new tetraorganotin(IV) complex, {bis(µ3-oxo)-bis(µ-isopropoxo)-dichloro-octakis(4-methyl)-tetra-tin, has been synthesized by dimethyltin dichloride in the presence of potassium iso peroxide. This Complex with a general formula of {(CH3)8Sn4Cl2(C3H7O)2O2} is classified in the category of tetraorganodistannoxanes. Solid state crystal structure of this compound  was determined  by single crystal X-ray diffraction. The titled complex is centerosymmetric and exists as a tetranuclear molecule which involves three staircase rings with a Sn4O4 core. The asymmetric unit of the complex contains two atoms of tin (IV) and an infinite two-dimensional structure is formed by CH...Cl interactions between tetranuclear units. Two types of bridged oxygen are present in this compound. One of them has an alkoxide nature and the other one is a bridge between three tin centers. The results of studies on tin multi-core systems have shown that in addition to the bulk effect, the size and the nature of different attached organic groups, the nature of the participating ligands in coordination environment influence the physical and chemical properties of these compounds.
