Zero field splitting and exchange interactions in bis(cyclopentadienyl)titanium(III) dinuclear compounds with short metal-metal distances: synthesis, x-ray structure, and EPR spectroscopy of methoxo- and ethoxo-bridged dimers

Abstract

The synthesis, crystal structure, and magnetic properties of [Cp 2 Ti(μ-OCH 3 )] 2 (1) (Cp=η 5 -C 5 H 5 ) and (Cp 2 Ti-(μ-OC 2 H 5 ) 2 (2) are described. The two compounds are obtained from [Cp 2 Ti(CH 3 ) 2 ] and trimethoxy- and triethoxysilane, respectively, in hexane. Both crystallize in the tetragonal system, space group P4n2.
