Harding, Phimphaka; Harding, David J.; Phonsri, Wasinee; Saithong, Saowanit; Phetmung, Hirihattaya published the article 《Synthesis and electrochemical studies of octahedral nickel β-diketonate complexes》. Keywords: nickel diketonate diimine ethylenediamine complex preparation; electrochem oxidation nickel diketonate diimine ethylenediamine complex; crystal structure nickel diketonate diimine ethylenediamine complex.They researched the compound: Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)nickel(II)( cas:14481-08-4 ).Category: esters-buliding-blocks. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:14481-08-4) here.
The reaction of [Ni(tmhd)2] and [Ni(dbm)2] (Htmhd = 2,2,6,6-tetramethylheptane-3,5-dione; Hdbm = dibenzoylmethane) with N-donor chelating ligands in CH2Cl2 and acetone, resp., yields [Ni(tmhd)2(L-L)] (L-L = 2,2′-bpy 1, phen 2 and dmae (2-dimethylaminoethyl)amine 3) and [Ni(dbm)2(L-L)] (L-L = 2,2′-bpy 4, phen 5, dmae 6). UV-visible spectroscopy shows very strong bands in the UV region consistent with ligand centered π → π* transitions. The electrochem. studies of 1-6 reveal oxidation to Ni(III). The [Ni(tmhd)2(L-L)] 1-3 are more easily oxidized by ∼300 mV and are quasi-reversible whereas for the [Ni(dbm)2(L-L)] series only complex 6 shows significant reversibility. X-ray crystallog. studies were conducted in the case of [Ni(dbm)2(phen)] 5 and [Ni(dbm)2(dmae)] 6. The structures both show that the Ni metal center is octahedral with an O4N2 coordination environment. In the structures the β-diketonate ligands exhibit a cis-arrangement, with the metal displaced out of the planar chelate ring.
