Synthesis and Structural Characterization of an Isomorphous Series of Bis(imidazolin-2-imine) Metal Dichlorides Containing the First Row Transition Metals Mn, Fe, Co, Ni , Cu, and Zn

Résumé

The bis(imidazolin-2-imine) ligand N,N'-bis(1,3-diisopropyl-4,5-dimethylimidazolin-2-ylidene)-1,2-ethanediamine (BLiPr) has been used to synthesize a complete series of transition metal dichloride complexes of the type [(BLiPr)MCl2] with M = Mn, Fe, Co, Ni, Cu, Zn. The molecular structure of each complex was established by X-ray diffraction analysis; the complexes are isomorphous and crystallize in the monoclinic space group C2/c, allowing a comparison of their structural parameters in a constant packing environment. The complexes exhibit distorted tetrahedral geometries around the metal atoms with the dihedral angles between the MN2 and MCl2 planes ranging from 53.9° (M = Cu) to 75.5° (M = Zn).
