资源简介：
A new heterometallic NiII–CuII decanuclear cluster, {[Ni4Cu6(μ-OH2)2(dpkO2)8(OAc)4(H2O)4]·2CH3OH·17H2O} (1), has been synthesized by self-assembly of the constituent metal ions and the precursor di-2-pyridylketone (dpk) of multinucleating ligand dpkO22– and is structurally characterized. The cluster 1 is formed by the union of two symmetry-related distorted cubane-like pentanuclear cores. A magnetic study of 1 reveals strong antiferromagnetic interactions operating through the Ni–O–Ni pathway, which is independent of the assumption D = 0 or D ≠ 0. The pentanuclear cores are ferromagnetically coupled, as supported by density functional theory calculations.
