Abstract

The bis-[β-carbonylenolato)nickel(II) complexes [Ni(eaa) 2] (eaa = ethylacetoacetato), [Ni(ba) 2] (ba = benzoylacetonato), [Ni(dbm) 2] (dbm = dibenzoylmethanato), [Ni(dpm) 2] (dpm = dipavaloylmethanato) are found to be reactive towards C 2N 2 to give selectively square-planar complexes of stoichiometry [Ni(ligand·C 2N 2) 2]. The reaction of [Ni(acac) 2] with C 2N 2 was re-considered and the nature of two supposed isomeric products has been thoroughly reinvestigated by a variety of physico-chemical methods, including a combination of thermogravimetry-differential thermal analyses. The complex [Niβ 2] (β = 1-cyano-2-(1-iminoethyl)butane-1,3-dionate) reacts quantitatively with [PdCl 2(PhCN) 2] to give a coordination polymer of approximate composition [(PdCl 2)(Niβ 2) 0.25]. © 1984.
