Rw. Gedridge et al., SYNTHESIS, CHARACTERIZATION, AND SOLID-STATE STRUCTURES OF THE 14-ELECTRON OPEN METALLOCENES M[1,5-(ME(3)SI)(2)C5H5](2) (M=TI OR ZR), Journal of organometallic chemistry, 501(1-2), 1995, pp. 95-100
Reactions of titanium(II) or zirconium(IV) chlorides with two or four
equivalents of K[1,5-(Me(3)Si)(2)C5H5], respectively, lead to the diam
agnetic 14-electron M[1,5-(Me(3)Si)(2)C5H5](2) complexes. Both have be
en characterized analytically, spectroscopically, and through single c
rystal X-ray diffraction studies.
