Abstract:
Three new pyridylbis(phenol) ligands with imine (H(2)L(imine)), amine (H(2)L(amine)), or amide (H(4)L(amide)) linkages, along with their copper complexes, were synthesized and characterized. Treatment of H(2)L(imine) with copper(II) in the presence of base produced mononuclear copper complex [Cu(L(imine))(MeOH)] (1), while the same procedure with H(2)L(amine) produced trinuclear [Cu(3)(L(amine))(2)(CH(3)CN)(2)](ClO(4))(2) (2). The more rigid H(4)L(amide) forms tetranuclear [Cu(4)(L(amide))(2)(H(2)O)(4)] (3), which upon recrystallization yielded crystals of hexanuclear [Cu(6)(HL(amide))(4)(H(2)O)(2)] (4).

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
