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 [Cu 2 L 2 ] 4+ . Reaction of [Cu 2 L 2 ] 4+ with dihydrogen phosphate (0.5 equivalents) gives the unsaturated dinuclear double helicate [Cu 2 L 2 (OPO 3 H 2 )] 3+ . [Cu 2 L 2 (OPO 3 H 2 )] 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 [{Cu 3 L 3 (OPO 3 H 2 ) 3 }] 26+ .
