  Co(II), Ni(II) and Cu(II) complexes of new [1+1] and [2+2] macrocyclic ligands derived from 1,4-bis(2′-formylphenyl)-1,4-dioxabutane and cis-1,2-diaminocyclohexane

  摘要：

  Two new macrocyclic ligands, L-1 (14-membered N2O2) and L-2 (28-membered N4O4) from [1+1] and [2+2] condensation, respectively, have been obtained in a one-pot synthesis starting from 1,4-bis(2'-formylphenyl)-1,4-dioxabutane and cis-1,2-diaminocyclohexane.Both ligands were synthesized in the same pot reaction in satisfactory yield and purity. The use of a washing and recrystallization processes allowed the separation of each macrocyclic ligand.No metal complexes were isolated with the small L-1 macrocycle. However, metal complexes with the 28-membered macrocycle L-2, using hydrated nitrate and perchlorate salts of transition Co(II), Ni(II) and Cu(II) metal ions, have been synthesized and characterized by microanalysis, LSI mass spectrometry, IR, UV-Vis spectroscopy, magnetic studies and conductivity measurements. Crystal structures of L-1, as well as [Co(HL2)(NO3)(2)(CH3CN)] (NO3) center dot 2CH(3)CN, [NiL2(NO3)](NO3) center dot 2H(2)O center dot CH3CN and [Cu2L2(NO3)(4)] center dot 4CH(3)CN complexes, have been determined. The X-ray studies show the presence of a hexacoordinated mononuclear exomacrocyclic complex for Co(II), whilst in the dinuclear Cu(II) complex both copper atoms are exocyclically coordinated by the nitrogen atoms from the ligand in a square planar environment. The crystal structure of [NiL2(NO3)](NO3) center dot 2H(2)O center dot CH3CN shows a mononuclear endomacrocyclic complex with the metal ion in a distorted octahedral environment.

  [CdL1](NO3)2 · 0.5H2O, [CdL1](ClO4)2 and [CdL2(CH3CN)2](ClO4)2 · CH3CN · H2O confirms the formation of mononuclear complexes in all cases. The [CdL1](NO3)2 · 0.5H2O and [CdL1](ClO4)2 present a mononuclear endomacrocyclic structure with the metal ion coordinated by the eight donor nitrogen atoms from the macrocyclic backbone in a square antiprism geometry.
