Synthesis and characterization of Co(II), Ni(II), Zn(II) and Cu(II) complexes with a new tetraazamacrocyclic Schiff base ligand containing a piperazine moiety: X-ray crystal structure determination of the Co(II) complex

Keypour, Hassan; Rahpeyma, Nasibeh; Arzhangi, Parisa; Rezaeivala, Majid; Elerman, Yalcin; Büyükgüngör, Orhan; Valencia, Laura (Pergamon-Elsevier Science Ltd, 2010)

Two macrocyclic Schiff base ligands, L-1 [1+1] and L-2 [2+2], have been obtained in a one-pot cyclocondensation of 1,4-bis(2-formylphenyl)piperazine and 1,3-diaminopropane. Unfortunately, because of the low solubility of ...
Synthesis and structural characterization of a new Schiff base macrocyclic ligand containing a piperazine head unit and its metal complexes. Crystal structure of the Co(II) complex

Keypour, Hassan; Rahpeyma, Nasibeh; Rezaeivala, Majid; Arzhangi, Parisa; Bayat, Mehdi; Valencia, Laura; Büyükgüngör, Orhan (Pergamon-Elsevier Science Ltd, 2013)

A new macrocyclic Schiff base ligand, L, was synthesized by the condensation reaction of 1,4-bis(2-formylphenyl)piperazine and 1,4-diaminobutane in acetonitrile. The Schiff base ligand was characterized by elemental analysis, ...
