A novel self-assembling synthesis and crystal structure of 40-membered macrocyclic complex containing eight-tin.

The self-assembly reaction of 2-mercapto-4-methyl-5-thiazoleacetic acid, sodium methoxide and dimethyltin dichloride in moist dichloromethane affords a novel eight-tin macrocyclic complex, which is a 40-membered macrocycle containing two distannoxane ladders.
