| Popis: | Coordination compounds of cobalt(II), nickel(II), and copper(II) with a poly nitrogen-containing heterocyclic ligand 1-(pyrid-2-yl)-1H-tetrazole (1-Pytz) such as [Cu(1-Pytz)2Cl2]n, [M(1-Pytz)2(H2O)Cl2] (M = Co, Ni), [M(1-Pytz)2(C2N3)2]n (M = Co , Ni) have been synthesized. The compounds have been studied by means of infrared diffuse reflectance spectroscopy, single-crystal and powder X-ray diffraction, and static magnetic susceptibility. The studies on the µeff(T) for the [Cu(1-Pytz)2Cl2]n, [Co(1-Pytz)2(C2N3)2]n and [Ni(1-Pytz)2(C2N3)2]n polynuclear complexes in the temperature range of 2–300 K have shown that exchange interactions between spins of metal ions are weak. |
