Mononuclear Cu(II) and triple helical dinuclear Co(II) complexes of a new potentially tetradentate ligand containing inequivalent bidentate units
摘要:
Reaction of the potentially tetradentate ligand L-4 with Co(ClO4)(2) gives the dinuclear triple helicate [Co-2(L-4)(3)](ClO4)(4) with the ligand L-4 partitioning into two N,N-bidentate units (phenanthroline and thiazolyl-pyridine); in contrast, reaction of L-4 with Cu(ClO4)(2) affords the mononuclear complex [Cu(L-4)(OH2)(ClO4)](ClO4) in which L-4 acts as a terdentate ligand via the phenanthroline and thiazolyl units, with the pyridyl group pendant but hydrogen-bonded to the water ligand.
