The title yttrocene, [Y-2(C14H15)(4)Cl-2] or [Y-2(cCp)(4)Cl-2] (cCp = cumylcyclopentadienyl), belongs to a class of complexes bearing pendant phenyl substituents which are potentially active as catalytic precursors in the stereospecific polymerization of olefins. In the crystal structure, the molecules possess a crystallographically imposed inversion centre and may be described as centrosymmetric mu-Cl-bridged dimers. No pi-aryl coordination to the metal is observed. A distorted tetrahedral coordination geometry is found around the two metal atoms.

Abstract
The title yttrocene, [Y-2(C14H15)(4)Cl-2] or [Y-2(cCp)(4)Cl-2] (cCp = cumylcyclopentadienyl), belongs to a class of complexes bearing pendant phenyl substituents which are potentially active as catalytic precursors in the stereospecific polymerization of olefins. In the crystal structure, the molecules possess a crystallographically imposed inversion centre and may be described as centrosymmetric mu-Cl-bridged dimers. No pi-aryl coordination to the metal is observed. A distorted tetrahedral coordination geometry is found around the two metal atoms.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
