摘要:
                                A series of metal complexes have been prepared using two similar ketiminato ligands, (ArLH)-H-1 (([RN(H)(C(Me))(2)C(Me)= O], ((R = 2,6-diisopropylphenyl (Dipp) or 2,6-dimethylphenyl, (Dmp)) and the less bulky, multidentate molecule (LH)-H-2, ([RN(H)C(Me)CHC(Me)= O] (R = C2H4NEt2)). Reaction of (ArLH)-H-1 or (ArLNa)-Na-1 with Co(SCN)(2), Eu(OTf)(3) and Cu(OTf)(2), afforded [Co(DippL(1)H)(2)(NCS)(2)] (1), [Eu(DippL(1)H)(3)(OTf)(3)] (2), and [Cu(OTf)(2)(DippL(1)H)(2)] (3). The coordination preferences of ArL1 and L-2 with FeBr2 were investigated and yielded crystals of [Fe(DippL(1))(2)] (4), [(LFeBr)-Fe-2 center dot LiBr(THF)(2)] (5), and [{(DmpN = C(Me))(2)C(H)Me}FeBr2] (6). Complexes 1-6 have been structurally characterized by X-ray crystallography, and other pertinent techniques. (C) 2010 Elsevier B.V. All rights reserved.
