Popis:	Two pseudosymmetrically related Ni II complexes are located in the asymmetric unit of solid [Ni(C 14 H 32 N 4 )](ClO 4 ) 2 . The Ni 2+ ion displays square-planar coordination with the four N atoms of the macrocyclic ligand. The quadridentate ligand adopts its stable conformation with two six-membered chelate rings in chair forms and two five-membered chelate rings in skew forms. The complex has a 1RS,4RS,8SR,11SR configuration for the four chiral N-atom centres and a 5SR,7RS,12RS,14RS configuration for the four chiral C-atom centres.
