The azamacrocyclic ligand 4â²-(p-1,4,7-triazacyclonon-1-ylmethylphenyl)-2,2â²â¶6â²,2â²â²-terpyridine (L) has been prepared, and some of the complexes it forms with hydrated copper(II) and nickel(II) have been isolated as the [PF6]â salts. X-Ray crystallography has been used to determine the solid state structure of the distorted trigonal bipyramidal complex [Cu(HL)(H2O)2][PF6]3, in which the copper(II) is co-ordinated to the terpyridyl group and the azamacrocycle is monoprotonated and non-co-ordinating. A bis(2,2â²â¶6â²,2â²â²-terpyridine)nickel(II) complex, [Ni(H2L2)2][PF6]6 has also been isolated, in which each azamacrocycle is diprotonated.
