Streszczenie

Reaction of nikiel (II) chloride with tetraethylenepentamine (tetren) and tetrabutylammonium hexachlororhenate [Bu4N]2ReCl6 produced a new kind of binuclear compounds: [Ni(tetren)]ReCl6 (1) and [Ni(tetren)]ReCl6·CH3OH (2) in which [ReCl6]2− anions and [Ni(tetren)]2+ cations are held united by electrostatic forces. The magnetic behaviour of 1 and 2 has been investigated over the temperature range 1.7–300 K. Compound 1 behaves as a ferrimagnetic NiII ReIV bimetallic, one-dimensional (1D) chain with intrachain antiferromagnetic coupling. A hysteresis loop characteristic of a soft magnet has been obtained. Compound 2 shows weak antiferromagnetic interactions within NiII–ReIV units.
