ТРИХЛОРИД ИНДЕНИЛЦИРКОНИЯ(IV) 97

Description

Indenylzirconium(IV) trichloride, 97% purity, is a half-sandwich organometallic complex of zirconium. Systematic name: trichloro[(1,2,3,3a,7a-η)-1H-inden-1-yl]zirconium; The indenyl ligand is bound to the metal according to the η⁵ type. The compound belongs to the precursors of metallocene catalysts: after activation with methylaluminoxane (MAO), complexes of this series give highly active systems for homogeneous polymerization of ethylene. Half-sandwich indenyl zirconium trichlorides also serve as a synthetic intermediate in the preparation of mixed-substituted metallocene dichlorides.

Storage and handling

Chloride complexes of transition metals are sensitive to moisture, so opening the container and sampling the sample is carried out in an inert atmosphere or in a dry box; the container is closed immediately. The substance is corrosive: gloves, safety glasses and a face shield are required (P280), in case of contact with eyes, rinse with water for a long time, remove contact lenses and seek immediate medical attention (P305+P351+P338, P310). Do not inhale dust (S22). Corrosive cargo, transportation according to UN 3261.
