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-η^2–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-η2–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.
