## Abstract The synthesis of a series of tetra‐ and pentadentate bispidine‐type ligands (bispidine=3,7‐diazabicyclo[3.3.1]nonane) – tetradentate ligands are donor‐substituted at C(2) and C(4), pentadentate ligands have an additional donor at N(3) or N(7), with pyridine, 2‐methylpyridine, or quinoli
## Abstract The pH‐dependent equilibria between Cu(II) and the potentially pentadentate ligands 4,7,10‐triazatridecane‐1,13‐diamine (__1__) and 1,9bis(2‐hydroxyphenyl)‐2,5,8‐triazanonane (**2**) have been studied in aq. solution at 298 K by EPR titration. Each ligand forms complexes CuLH~x~ (x=1,2,
