85% General procedure: A general method was followed for the synthesis of complexes1-3. In a typical procedure, a mixture of nBuSn(O)OH and theappropriate ligands (HL1, HL2 or HL3) in a 6:6 stoichiometric ratiowas heated to reflux in anhydrous toluene (50 mL) for 8 h in around bottom flask equipped with a Dean-Stark apparatus and awater cooled condenser. The reaction mixture was filtered whilehot and the solvent was removed using a rotary evaporator. Theresidue was washed, boiled with hexane, filtered and dried invacuo. The residue upon crystallization using appropriate solvent(s) yielded the desired product. The specific details pertaining toreactants, analytical and characterization data for the complexesare given below. 2.4.1.1. Synthesis of [nBu6Sn6O6(L1)6].C8H10 (1). nBuSn(O)OH (0.53 g,2.54 mmol); HL1 (0.35 g, 2.55 mmol). Recrystallized from p-xyleneto give pale yellow microcrystalline product in 85% yield. M.p.:315-317 C.

79% In toluene;Reflux; Dean-Stark; General procedure: A general method was followed for the synthesis of complexes1-3. In a typical procedure, a mixture of nBuSn(O)OH and theappropriate ligands (HL1, HL2 or HL3) in a 6:6 stoichiometric ratiowas heated to reflux in anhydrous toluene (50 mL) for 8 h in around bottom flask equipped with a Dean-Stark apparatus and awater cooled condenser. The reaction mixture was filtered whilehot and the solvent was removed using a rotary evaporator. Theresidue was washed, boiled with hexane, filtered and dried invacuo. The residue upon crystallization using appropriate solvent(s) yielded the desired product. The specific details pertaining toreactants, analytical and characterization data for the complexesare given below.

99.4% In water; at 60.0℃; for 2.5h; 11 g of Na2CO3 was weighed into a reaction flask and stirred with 200 g of water,Add 200g of ammonia concentration of 20% of the reaction flask into the water bath to 60 ; weighing 0.9g additives diluted with 20g water after 50% added to the reaction bottle; weighed 100g monobutyltin trichloride liquid into the Constant pressure funnel slowly into the reaction bottle, and then constant temperature reaction 2h. During the incubation process, 20% of the diluted additive was added every 30 minutes. After the completion of the reaction, the monobutyl tin oxide obtained by the reaction was filtered through a cloth funnel, and the filter cake was transferred to a 500-M beaker and heated to about 200 ml of water. The washing temperature was controlled at 60 to 65C, The resulting filter cake was dried with a rotary evaporator at a drying temperature of 85 to 95 C to finally obtain 73.78 g of monobutyltin oxide in a yield of 99.4%.

65% In toluene; for 8.0h;Reflux; Dean-Stark; A mixture of n-BuSn (O) OH (0.030 g, 0.14 mmol), ligand HL (0.100 g, 0.14 mmol), toluene 30ML, 10 mL of ethanol was heated under reflux in a Dean-Stark apparatus for 8 hours and the reaction was removed by azeotropic distillation Generated water. The solution was then distilled under reduced pressure to give a white solid. With a 1: 1 by volume mixture of chloroform and ethanolRecrystallization at room temperature gave colorless crystals in 65% yield.
