On the existence of the anion trichloro(η-cyclopentadienyl)titanate(1–). Crystal structure of the salt [Co(C5H5)2][Ti(C5H5)Cl3]
Abstract
We have isolated, and characterised by elemental and X-ray crystal structure analysis, and e.s.r. and n.m.r. spectroscopy, the salt [Co(C5H5)2][Ti(C5H5)Cl3]. The results show that the ion [Ti(C5H5)Cl3]– is a stable species of not unexpected properties, despite an earlier report that it readily loses chloride. This represents the first structural analysis of a (cyclopentadienyl)trihalogenotitanate(1–) species.
