Abstract
The reactions of hafnocene dichloride with 2-thiophenecarboxylic acid (2-TCH), 2-thiopheneacetic acid (2-TAH), 3-thiophenecarboxylic acid (3 -TCH), 3-thiopheneacetic acid (3-TAH), and 4-(2)-thienylbutyric acid ( 2-TBH) in various stoichiometric ratios have been studied, and complex es of the type Cp2Hf(L)Cl and CpHf(L)2Cl (where L is the bidentate thi ophenecarboxylate ion) were obtained. Magnetic susceptibility data sug gest that these complexes are diamagnetic.
