Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The amine‐containing ligand L, composed of two bidentate pyridyl‐thiazole moieties linked by a 1, 3‐diaminophenylene unit, reacts with copper(II) ions to form a dinuclear double helicate [Cu₂L₂]⁴⁺. Reaction of [Cu₂L₂]⁴⁺ with dihydrogen phosphate (0.5 equivalents) gives the unsaturated dinuclear double helicate [Cu₂L₂(OPO₃H₂)]³⁺. [Cu₂L₂(OPO₃H₂)]³⁺ further reacts with another 0.5 equivalents of dihydrogen phosphate to give a trinuclear circular helicate which then self‐assembles into a hexameric cluster [{Cu₃L₃(OPO₃H₂)₃}]²⁶⁺.</p> </abstract>
