Notes
†Synthesis of {[nBu2Sn(LH)]2O}2 (1); The reaction was carried out under a nitrogen atmosphere using standard Schlenk techniques. A suspension of nBu2SnO (0.46 g, 1.84 mmol) and LHH′ (0.5 g, 1.85 mmol) in 50 ml anhydrous toluene was refluxed for 10 h in a flask equipped with a Dean-Stark water separator and a water-cooled condenser. The orange coloured solution was filtered while hot and solvent evaporated from the filtrate in vacuo to give an orange residue that was washed thoroughly with

2021, Inorganic Chemistry CommunicationsCitation Excerpt :As an important part of metal-based complexes, organotin derivatives exhibit abundant structural diversity, which have received great attention for a long period [1–5]. Up to now, a number of organotin derivatives with various structures, such as cubes, butterflies, ladders, drums, and polymers have been constructed [4–8]. For example, the tetrameric n-butyloxotin di-tert-butylphosphinate displays a cubic cluster [8], the dimeric n-butylhydroxytin bis(dicyclohexylphosphinate) is a “butterfly” cluster [8], and the 4-carboxybenzenesulfonamide diorganotin(IV) complexes adopt tetranuclear tin ladder-like structure containing two deprotonated ligands linked by three alternate Sn2O2 four-membered rings [9].
