The synthesis and structure of a macrocyclic dinickel complex incorporating a hypercoordinated sulfenium(II) cation are reported. The novel complex [Ni2L3(Cl)]2+ was obtained from a reaction of the per-hydroxyethylated N6S2 macrocycle H2L2 with NiCl2(H2O)6 in the presence of air, and isolated as its ClO4 or BPh4 salt. The structure reveals a three-coordinate sulfenium cation that is stabilized by two intramolecularly coordinating amino groups. The N-S bonds are 2.087(7) Å and 2.105(6) Å and the N-S-N bond angle is 168.2(2)°. The bonding is best described by a N,N-chelated sulfur(II) atom (3c-4e bond) bearing two lone pairs and a formal charge of +1
