A hexanuclear metallamacrocycle complex [Ni( i Pr 3 tacn)(dca)(PF 6 )] 6 ( 1 ) was obtained by using the tridentate ligand 1, 4, 7‐triisopropyl‐1, 4, 7‐triazacyclononane ( i Pr 3 tacn) 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 .
