According to the H NMRstudy, it was found that the protons on the cyclopentadienyl ring of 〓 were not splitted, but when one proton on the cyclopentadienylring was substituted by methyl, that is in〓 complexes, thefour protons on the ring were splitted into four groups,the 〓 between the onesignal and the others is large, the total splitting is over 2ppm. The splittings werealso affected by the halides linked with the titanium, they increase according to theorder of CI, Br, I. By the study of the 〓 Sn NMR, it is found that the chemicalshifts of 〓 are present in low field. It is assume that the large space strain causesthe angles of the tin linked with ligands deviate from the normal tetrahedral anglesresults low field shift for 〓Sn. And by MS study,there were no molecular ions for 〓 complexes in the spectra. However, for 〓 when X=CI,Br,NCO and Ar is tolyl or phenyl group,there were molecular ions,but theirabundances were very small,and no that for the iodide was found.
钛上的卤素对茂环氢的裂分也有影响，依〓，Br，I顺序，卤素对茂环氢的裂分依次加大；通过对〓的研究发现，以上这些化合物〓的化学位移都出现在低场，认为大的空间张力造成的锡的键角偏离正常的锡的四面体键角是造成〓化学位移出现在低场的原因；对这些化合物质谱的研究发现，〓系列化合物得不到分子离子峰，而〓系列的化合物，当X=〓，NCO和苯环上不带取代基或只带甲基时，则出现分子离子峰，但丰度很低，而相应的碘化物和其它化合物则没出现分子离子峰。
