Synthesis Properties and Biological Activity of Organotitanium Substituted Heteropolytungstates

摘要

Six new compounds [(CpTi)X, Cp=ϋ^∇-c∇H∇, X=Ge, Ga, B) have been prepared and their Keggin structures determined by elementary analysis, IR, UV, ^∞H NMR and ^∞∀∊WNMR spectrometry. The results show that the complexes retain Keggin structure. The complexes exhibit antitumoral activity in vitro as shown by MTT experiment.
