(Pergamon-Elsevier Science Ltd, 2012)
Polymeric copper(II) complex, [Cu(Hacm)(2)(na)(2)(H2O)(2)] [H(2)acm: acetazolamide, na; nicotinamide] was synthesized and characterized by spectroscopic (IR; infrared spectroscopy, EPR: electron paramagnetic resonance), ...
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
(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 ...
