A discrete unsymmetrically substituted dihydrodioxadistannetane with both η1 and intramolecular η2μ2 sulfonate bondings
چکیده انگلیسی

Hydrolysis of the aryltripropynyltin (3) in the presence of an arylsulfonic acid resulted in the formation of a new tetrasulfonato 1,3-dihydro-1,3-dioxa-2,4-diaryl-2,4-distannetane (4). Its crystal structure revealed that the molecule is the smallest discrete tin sulfonate cluster reported up to now with absence of intermolecular interactions. Molecule 4 also exhibits unusual η1 and intramolecular η2μ2 bonding modes for the sulfonate groups. Moreover, while only symmetrical 1,3-dihydro-1,3-dioxa-distannetanes have been described so far, the tin atoms in 4 are differently substituted.
