## Abstract The preparation of a macrocyclic diphosphine ligand 5 incorporating a binaphthyl unit and its Ni^II^ and Pd^II^ complexes, 6 and 7, is described. A complete assignment of ^1^H,β ^13^Cβ, and ^31^PβNMR data on the basis of 2D NMR spectroscopy (^1^H, ^1^Hβ, ^13^C, ^1^Hβ, ^31^P, ^1^Hβ, ^31^
Nickel(II) complexes of mono-and bis(macrocyclic) ligands are the products of a nickel(II)-assisted template reaction with 2,3,2-tet, melamine and formaldehyde [2,3,2-tet = bis-N,NΠ-(2-aminoethyl)propane-1,3-diamine; melamine = 2,4,6-triamino-1,3,5-triazine]. The structures of two four-coordinate, d
