A 1 : 1 mixture of the homoleptic double helicates [M-II(L-1)(2)] and [M-II(L-2)(2)] [M = Cu, Zn; (L-1)(2-) and (L-2)(2-) are bis-bidentate ligands containing two pyrazolyl-phenolate termini but with different spacers separating them] affords the mixed ligand complexes [M(L-1)(L-2)] in high yield, indicative of a favourable inter-ligand interaction in the mixed-ligand complexes. Whereas [Cu(L-1)(L-2)] is a double helicate, [Zn(L-1)(L-2)] is a mesocate with a 'face to face' arrangement of the two ligands.
