A Disc-Like Heptanuclear Nickel Cluster Based on Schiff Base: Synthesis, Structure, Magnetic Properties and Hirshfeld Surface Analysis
2016
A new disc-like heptanuclear cluster [Ni7(immep)6(MeO)6]·(NO3)2 (1, Himmep is 2-imminomethyl-6-ethxoy-phenol) was synthesized through microwave assisted reaction of Ni(NO3)2·6H2O with 2-hydroxy-3-ethoxy-benzaldehyde and ammonium water in mixed solvent (acetonitrile:methanol = 1:1). 1 was characterized by IR spectroscopy, elemental analysis and X-ray single-crystal diffraction. Magnetic property of 1 was discussed. The core of 1 displays dominant ferromagnetic interactions from the nature of the binding modes through μ 3-OCH3. According to the 3D Hirshfeld surface and 2D fingerprint plots, the main interactions in 1 are the H···H, O···H, and C···H contacts.
