The tautomeric equilibrium between the azo type and the hydrazone type of these compounds in different solvents and different acidity has also been studied. 对它们在不同溶剂。不同酸碱度溶液中的偶氮式及腙式间互变异构平衡进行了研究。
The results of the studies indicate that the tautomeric equilibrium between the enol imine and keto enamine exists in the compounds. 结果表明,合成的化合物具有醇亚胺和酮胺互变异构体结构,锡原子是五配位的,存在着分子间酚羟基(酮羰基)氧原子同锡原子的配键。
