| Abstract: | A series of metal complexes have been prepared using two similar ketiminato ligands, ArL1H ((RN(H)(C(Me))2C(Me) O], ((R = 2,6-diisopropylphenyl (Dipp) or 2,6-dimethylphenyl, (Dmp)) and the less bulky, multidentate molecule L2H, (RN(H)C(Me)CHC(Me)O] (R = C2H4NEt2)). Reaction of ArL1H or ArL1Na with Co(SCN)2, Eu(OTf)3 and Cu(OTf)2, afforded Co(DippL1H)2(NCS)2] (1), Eu(DippL1H)3(OTf)3] (2), and Cu(OTf)2(DippL1H)2] (3). The coordination preferences of ArL1 and L2 with FeBr2 were investigated and yielded crystals of Fe(DippL1)2] (4), L2FeBr·LiBr(THF)2] (5), and {(DmpNC(Me))2C(H)Me}FeBr2] (6). Complexes 1-6 have been structurally characterized by X-ray crystallography, and other pertinent techniques. |
