摘要
A hexanuclear metallamacrocycle complex [Ni(iPr3tacn)(dca)(PF6)]6 (1) was obtained by using the tridentate ligand 1, 4, 7-triisopropyl-1, 4, 7-triazacyclononane (iPr3tacn) and the flexible ligand dicyanamide (dca). The complex was characterized by X-ray crystallography and magnetic measurements. Complex 1 contains hexacyclic rings adopting chair conformation, which can be described as metallamacrocycle. Variable-temperature magnetic measurements reveal antiferromagnetic interactions across the single end-to-end dca bridges in compound 1.
