Influence of the amino substituents of potentially bis ortho chelating aryl ligands (2,6- l brace R sup 1 R sup 2 NCH sub 2 r brace sub 2 C sub 6 H sub 3 ) sup minus on the synthesis and properties of their organonickel(II) complexes

Two series of square-planar organometallic Ni(II) complexes that contain various monoanionic, potentially terdentate ligands (2,6-{l brace}R{sup 1}R{sup 2}NCH{sub 2}{r brace}{sub 2}C{sub 6}H{sub 3}){sup {minus}} (=R{sup 1}R{sup 2}NCN{prime}) have been synthesized. In one series this ligand is terdentate bonded to the Ni(II) center via C(ipso) and the two N donor atoms. In the other series, the Ni(II) center is bonded to a halide anion, to two phosphorus ligands, and to only C(ipso) of the R{sup 1}R{sup 2}NCN{prime} ligand. The molecular structures of three complexes have been determined by X-ray crystallographic methods and the results are reported herein. The ligand strength of the various amino groups toward the Ni(II) center decreases in the order Me{sub 2}N > Et{sub 2}N > (i-Pr)MeN > (t-Bu)MeN > (Ph)MeN. Resonance Raman spectroscopic data indicate that in solution the complexes (NiI(Et{sub 2}NCN{prime})) and (NiI((i-Pr)MeNCN{prime})) interact with added I{sub 2}. 45 refs., 6 figs., 10 tabs.
