title: Synthesis, properties and biological activity of organotitanium substituted heteropolytungstates.
abstract: Six new compounds [(CpTi)X, Cp=upsilon(nabla)-c(nabla)H(nabla), X=Ge, Ga, B) have been prepared and their Keggin structures determined by elementary analysis, IR, UV, (infinity)H NMR and (infinity for all)WNMR spectrometry. The results show that the complexes retain Keggin structure. The complexes exhibit antitumoral activity in vitro as shown by MTT experiment.
