Synthesis of the terpyridyl pendant-arm azamacrocycle 4 '-(p-1,4,7-triazacyclonon-1-ylmethylphenyl)-2,2 ': 6 ',2 ''-terpyridine (L) and complexes of L with copper(II) and nickel(II). Crystal structure of [Cu(HL)(H2O)(2)][PF6](3)

摘要

The azamacrocyclic ligand 4'-(p-1,4,7-triazacyclonon-1-ylmethylphenyl)-2,2':6',2 "-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](-) 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(2,2':6',2 "-terpyridine)nickel(II) complex, [Ni(H2L2)(2)][PF6](6) has also been isolated, in which each azamacrocycle is diprotonated. [References: 17]
