Abstract
The complex )(2)Ti(eta(1)-C=CC=CSiMe(3))(2)](-)[Li(THF)(2)](+) (1) was obtained by the reaction of (C(5)HMe(4))(2)TiCl with 2 equiv. of LiC= CC=CSiMe(3) in THF. X-Ray crystal structure determination of 1 reveale d that the lithium ion is embedded between the inner triple bonds of t he 4-trimethylsilyl-1,3-butadiyn-1-yl tweezer arms. The EPR spectrum o f 1 shows a single line, Delta H = 2.5 G at g = 1.9940 (+/-0.0003), an d coupling to Ti-49 and Ti-47 isotopes a (Ti)= 7.5 G.
