Abstract
The reduction of (C5Me4Ph)(2)TiCl2 by magnesium in tetrahydrofuran affords a mixture of the diamagnetic doubly tucked-in titanocene complex (C5Me4Ph) [C5Me2(CH2)(2)Ph]Ti (1), the paramagnetic trinuclear Ti-Mg-Tihydride bridge d complex[(C5Me4Ph)(2)Ti(mu-H)(2)](2)Mg (2) and the paramagnetic binuclear titanocene hydride-magnesium hydride complex (C5Me4Ph) [C5Me4(o-C6H4)]Ti(mu -H)(2)Mg(THF)(2) (3). The X-ray diffraction analysis of 3 revealed that the magnesium atom forms the sigma-bond to the ortho-carbon atom of one of the phenyl rings and binds 2 molecules of THF.
