A novel bonding mode of oximato ligand to a metal; synthesis and X-ray crystal structure of bis[acetone oximatobis(cyclopentadienyl)gadolinium][{(C5H5)2Gd(µ-η2–ONCMe2)}2]

Abstract

Reaction of [Cp₃Gd](Cp = C₅H₅) with acetone oxime in THF at room temp. results in the formation of a new complex [{Cp₂Gd(µ-η^2–ONCMe₂)}₂]; X-ray analysis shows an unusual structure with the O–N fragment of ONCMe₂ ligand acting as both a bridging and side-on donating group.
