Preparation and Properties of a Series of [Cr2Ln2] Oximato-Bridged Complexes



A series of new [Cr2Ln2] (Ln = La, Ce, Pr, Nd, Sm, Eu) complexes 16 is reported with phenyl 2-pyridyl ketoxime (ppkoH) acting as a ligand and with a new oximato-bridged butterfly-like complex core. Compounds 16 were characterized mainly by X-ray diffraction studies, EDX, elemental analyses, IR spectroscopy and studies of magnetic properties, the latter showing negligible coupling of the Cr3+ ions in 1.
