The effect of systematic variation of the donor-atom set within dibenzo-substituted, 17- to 20-membered macrocycles on their ability to discriminate between silver(I) and lead(II) has been investigated. The log K values for the respective complexes. determined potentiometrically in 95% methanol (l = 0.1 mol dm(-3), NEt(4)ClO(4)), show that successive replacement of either nitrogen or oxygen heteroatoms by thioether donors leads to increasing affinity for silver(I) relative to lead(II), as does the incorporation of an 'aliphatic' NON or NSN donor sequence in the structure. For the 17-membered system incorporating a S2N2S-donor set, exceptional discrimination (of the order of 10(9)) was observed. The characterisation of selected complexes has included the crystal structure of the sliver perchlorate complex of the 17-membered ON2S2 macrocycle (L(17)). The silver ion in [AgL(17)]ClO4 has a very distorted trigonal-bipyramidal geometry with all metal to donor bond lengths appearing normal. The complex crystallises in the monoclinic space group P2(1)/n with lattice parameters a = 19.410(4), b = 9.602(2), c = 12.747(3) Angstrom, beta = 103.67(2)degrees and Z = 4.

The interaction of Cu2+ with three new O2N3-donor macrocycles has been investigated. Complexes of the type CuL(ClO4)2.nH2O and CuLX(ClO4).nH2O (where L = macrocycle, X = Cl or Br, and n= 0, 1, or 2) have been isolated. Conductance studies indicate that the halide ions in the latter complexes are co-ordinated in dimethyl sulphoxide. All complexes show the expected magnetic moments for Cu2+ with S=½
