摘要：
The reactions of sodium and thallium catecholates CatM(2) (Cat is the 3.6-di-tert-butylpyrocatechol dianion; M = Na, Tl) with tin diphenyl dichloride afford new tin catecholate complexes Ph(2)SnCat center dot THF (I) and Ph(2)SnCat (II). The molecular structure of pentacoordinated complex I is determined by X-ray diffraction analysis. The synthesized complexes are capable of fixating both short-lived (PhC(O)O-center dot, (CH3)(2)NC(S)S-center dot, and NC(CH3)(2)C-center dot) and stable free radicals (aroxyl, nitroxyl, triphenylmethyl, and phenoxazinyl) to form stable o-semiquinone tin derivatives.
