| 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. |
