Description: The four-strand and potentially N₂O₂-donor ligand 2,3-endo,endo-bis(aminomethyl)-5,6-endo,endo-bis(hydroxymethyl)bicyclo[2.2.1]heptane (L1), a close analogue of the known tetraalcohol 2,3,5,6-endo,endo,endo,endo-tetrakis(hydroxymethyl)bicyclo[2.2.1]heptane (L2), has been prepared via a multi-step synthesis and isolated as the copper(II) complex [Cu(L1)₂](ClO₄)₂. An ESI-MS study of the complex and metal ion exchange with other transition metal ions (Fe²⁺, Co²⁺, Ni²⁺, Mn²⁺ or Zn²⁺) indicates that 1:1 complexes form readily. Apparently special stability for the Ni²⁺ species observed in the ESI-MS study suggests strong encapsulation of this ion.
