 Title    Zirconium Reagents for Organometallic Synthesis. Crystal Structures of ZrCl4*2Et20 and (Et2N)ZrCl3*Et20  
 Abstract    Reaction of 3 equivalents of ZrCU-2Et20 (1) with 1 equivalent of (Et^N ^Zr in diethyl ether readily affords crystalline (Et2N)ZrCl3-2Et20 (2) in almost quantitative yield. The product was characterised by elemental analysis and by 1H. 1 C NMR, and MS techniques. The reactivity of this reagent towards C-H acidic compounds has been studied using cyclopentadiene as a C-H acid. The crystal structures of both 1 and 2 have been determined by X-ray diffractometry. The coordination polyhedra reveal a nearly perfect octahedral geometry with a trans Et20 ligation for 1 and a cis one for 2.

Their analyses, general properties, IR-spectra and structures are reported briefly. E x ­ periments to crystallize a compound with a ratio N : I : chinuclidin = 1:4:1 resulted in the preparation of cristallized chinuclidiniumpentaiodide (chin H)l3 -l2 , the X-ray structure analysis of which is reported.
