New Tetracopper(II) Cubane Cores Driven by a Diamino Alcohol: Self-assembly Synthesis, Structural and Topological Features, and Magnetic and Catalytic Oxidation Properties.

Two new coordination compounds with tetracopper(II) cores, namely, a 1D coordination polymer, [Cu4(μ4-H2edte)(μ5-H2edte)(sal)2]n·10nH2O (1), and a discrete 0D tetramer, [Cu4(μ4-Hedte)2(Hpmal)2(H2O)]·7.5H2O (2), were easily self-assembled from aqueous solutions of copper(II) nitrate, N,N,N',N'-tetrakis(2-hydroxyethyl)ethylenediamine (H4edte), salicylic acid (H2sal), or phenylmalonic acid (H2pma). The obtained compounds were characterized by IR and electron paramagnetic resonance spectroscopy, thermogravimetric and elemental analysis, and single-crystal X-ray diffraction.
