A fundamentally novel type of complex‐ligand is exemplified by the triply bridged hexalactam structure and octahedral donor geometry. The ligand dissolves stainless steel, iron, chromium, and nickel to form colored, stable complex anions of type 1 , which are not even decomposed by excess EDTA. 1:1‐Stoichiometry has been demonstrated for the iron( III ) complex.—Almost 1 g of ligand can be conveniently obtained per charge.
