Synthesis,structural characterization,and magnetism of a butterfly-shaped hexanuclear Ni(II) complex

摘要

A new butterfly-shaped hexanuclear complex [Ni6L4H2O(C5H5N)4] · 2DMF (L=anion of N-(3-t-buty-lbenzoyl)-5-bromosalicylhydrazide) has been synthesized and characterized structurally and magnetically,which contains two trinuclear [Ni3L2(py)2] subunits bridged by two mu2-O(carbonyl) and one mu2-O(H2O) groups.It exhibits obvious ferromagnetic interaction owe to the central Ni(II) dimer with octahedral geometries.
