A set of new dicyclopentadienyl titanium complexes was generated by the reactions of titanocene dichloride with sterically impeded heterocyclic beta-diketones (L(1)H=4-acetyl-2,4 dihydro-5-methyl-2-phenyl-3H-pyrazol-3-one, L(2)H=4-propanoyl-2,4 dihydro-5-methyl-2-phenyl 3H-pyrazol-3-one and L(3)H=4-(4-chloro)benzoyl-2,4 dihydro-5-methyl-2-phenyl 3H-pyrazol-3-one), beta-diketones (L'(1)H=pentane-2,4-dione, L'(2)H=1-phenylbutane-1,3-dione and L'(3)H=1,3-diphenylpropane-1,3-dione) and triethylamine in 1:1:1:2 molar ratio in refluxing dry THF. Plausible structures of these newly generated complexes were suggested based on spectroscopic and mass studies. Some representative complexes were also screened for their antimicrobial activity.
