Abstract

N,N′-dioxide ligands such as 2, 2′-bipyridine-N,N-dioxide (BPDO-I) and 4, 4′-bipyridine-N,N-dioxide (BPDO-II) were used to trap the hydrated dimethyltin cations under controlled hydrolysis. The use of the chelating ligand BPDO-I leads to the isolation of the discrete monocation [Me2Sn(BPDO-I)(OH2)(NO3)]+[NO3]– (2), whereas the linear ligand BPDO-II directs the construction of cationic polymers, [{Me2Sn(OH2)2(μ-BPDO-II)}2+{NO3–}2·2H2O]n (3·2H2O) and [{Me2Sn(μ-OH)(BPDO-II)}22+{NO3–}2·H2O]n (4·H2O) under different reaction conditions.
