Three new homo- and heterotrimetallic complexes were synthesized and crystallog. characterized: [Cu2(saldmpn)2(μ-OCH3)2Cu2(hfac)2] (1), [Ni2(valaepy)2(hfac)2] (2), [Cu(saldmpn)Co(hfac)2] (3) [H2saldmpn is the Schiff-base resulting from condensation of salicylaldehyde with 2,2-dimethyl-1,3-diaminopropane and Hvalaepy results from the reaction of o-vanillin with 2-(2-aminoethyl)pyridine]. The structure of consists of a neutral tetranuclear species that can be viewed as resulting from mutual coordination of one {(hfac)Cu(μ-OCH3)2(Cu(hfac))} and two {Cu(saldmpn)} building blocks. Compound is a binuclear complex that results from two {Ni(hfac)(valaepy)} fragments, the nickel(II) ions bridged by the two phenoxide-oxygens. The heterobinuclear complex results from coordination of the [Cu(saldmpn)] metalloligand to cobalt(II) from the {Co(hfac)2} unit. The magnetic properties of were studied from 1.9 to 300 K. An overall ferromagnetic behavior is observed for and leading to S = 2 low-lying spin state for each. In the case of, a non-magnetic ground state results because of the occurrence of an intramol. antiferromagnetic coupling between the copper(II) ion and the high-spin cobalt(II) ion, this last one behaving as an effective spin Seff = 1/2 at low temperatures where only the ground Kramers doublet of Co(II) is thermally populated. The values of the intramol. magnetic couplings in are compared with those from the literature on related systems. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Related Products of 14781-45-4).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant. These ligands enable the reaction promoted in mild condition. The reaction scope has also been greatly expanded, rendering this copper-based cross-coupling attractive for both academia and industry. Related Products of 14781-45-4
