The syntheses via metall-ion (Mg(2+), Ca(2+), or Ba(2+)) template methods followed by transmetallation, of the complexes (ML1)X2 (M=MnII, FeII, CoII, NiII, CuII, or ZnII; X=ClO4(1-) or BPh4(1-)) of the potentially septidentate ligand L1 formed by condensation of 1 mol of 2,6-diacetylpyridine with 2 mol of 3-oxapentane-1,5-diamine is described.The collective evidence of the properties (magnetic and spectroscopic) of the complexes indicates a seven-co-ordinate (pentagonal-bipyramidal) structure.Ring closure, via a transamination mechanism, of L1 in BaL1(ClO4)2 leads to the complex BaL2(ClO4)2*3H2O containing the 24-membered N6O2 macrocyclic ligand L2.The single Ba(2+) in this complex may be replaced by two copper(II) ions to afford the binuclear complex Cu2L2(ClO4)4*H2O which on treatment with imidazole (Him) gives Cu2L2(im)(ClO4)3*H2O containing an imidazolate bridge between the antiferromagnetically coupled metal centres.
