  Intramolecular hydrogen-bond formation in nickel(II) complexes with macrocyclic ligands containing non-co-ordinating nitrogen atom(s): new ditopic receptors differentiating hydrogensulfate and hydrogenphosphates

  摘要：

  A comparative study of a series of nickel(II) complexes with structurally related tetradentate 14-membered tetra-, penta- and hexa-aza macrocycles has shown that the non-co-ordinating (remote) nitrogen atoms in the ligand backbones drastically influence the solution equilibria between the four-and six-co-ordinated forms of the complexes. This phenomenon is interpreted in terms of the formation of intramolecular. along with co-ordinative, hydrogen bonds between the axial ligand and remote nitrogen. Such specific two-centred interactions result in relatively high formation constants of mono(hydrogensulfate) complexes [NiL(HSO4)(H2O)](+). For the tricyclic complex, with L = 1,3,6,9,11,14-hexaazatricyclo[l2.2.1.1(6,9)]octadecane, the formation of both mono- and bis-(hydrogensulfate) adducts has been detected with K-1 = 7 +/- 1 and K-2 = 36 +/- 5 dm(3) mol(-1), thus indicating the allosteric effect in this system. The high differentiating effect for hydrogensulfate versus hydrogenphosphates, which is especially evident for the tricyclic complex, has been established.
