Self‐assembly of nickel ions and the N 4 Schiff base H 2 PTs [ H 2 PTs : N , N′ ‐bis(2‐tosylaminobenzylidene)‐1,3‐diaminopropane] in an electrochemical cell leads to the novel neutral double‐stranded dinuclear helicate [NiPTs] 2 ·CH 3 CN ( 1 ). Complex 1 was fully characterised by elemental analysis, IR and EPR spectroscopy, FAB mass spectrometry, and magnetic measurements. The single X‐ray crystal structure of 1 shows that both ligands are asymmetrically positioned around the Ni−Ni axis, leading to a double‐helical complex that presents a major and a minor groove.
