N2 - Mixed-ligand Ni(II) complexes involving thiodiglycolate(2-) anion (tdga) and nitrogen-donor ligands in the coordination sphere have been prepared. The complexes of composition [Ni(bpy)(tdga)(H2O)].4H2O (1), [(en)Ni(-tdga)2Ni(en)].4H2O (2), [Ni(phen)(tdga)(H2O)] (3), [Ni(1,8-dan)(tdga)(H2O)] (4), [Ni(nphen)(tdga)(H2O)].H2O (5), [Ni(ampy)(tdga)(H2O)] (6), where BPY=2,2Ąä-bipyridine, EN=ethylenediamine, PHEN=1,10-phenanthroline, 1,8-dan=1,8-diaminonaphthalene, NPHEN=5-nitro-1,10-phenanthroline and AMPY=2-(aminomethyl)-pyridine, have been characterized by elemental analysis, IR and UV-Vis spectroscopies, and magnetic susceptibility measurements. Room temperature effective magnetic moments for 1-6 are ranging from 3.06 to 3.28 mu eff/mu B. and thus indicating that nickel atoms are six-coordinated in a deformed octahedral arrangement in all the prepared complexes. This conclusion has been confirmed by single-crystal X-ray analysis of [Ni(bpy)(tdga)(H2O)].4H2O (1). A binuclear structure of complex [(en)Ni(mu-tdga)2Ni(en)].4H2O (2) has been anticipated in connection with study of its magnetic properties over the 1.8-300 K temperature range (J=-4.35 cm-1, D=5.53 cm-1, zJ=-0.94 cm-1 for g=2.00) and unambiguously proved by a single-crystal X-ray analysis.
