A ferromagnetic complex [BrFBzPy][Ni(mnt)2], where [BrFBzPy]+ = 1-(4′-bromo-2′-fluorobenzyl)pyridinium and mnt2-= maleonitriledithiolate, has been prepared. The [Ni(mnt)2]- anions and [BrFBzPy]+ cations form a well-separated stacking column and [Ni(mnt)2]- anions are uniformly spaced to give a one-dimensional (1-D) chain structure. Its magnetization studies shown it ferromagnetically ordered around 2 K.

A novel ferromagnetic complex [BrFBzPy][Ni(mnt)2], where [BrFBzPy]+ = 1-(4′-bromo-2′-fluorobenzyl)pyridinium and mnt2- = maleonitriledithiolate, has been prepared and characterized. In the crystal structure the most prominent feature is that the [Ni(mnt)2]- anions and [BrFBzPy]+ cations form a well-separated stacking column along the c-axis, within which the [Ni(mnt)2]- anions are uniformly spaced to give a one-dimensional (1-D) chain structure. The magnetic properties of this complex have been investigated in the temperature range 1.8-300 K and its magnetization studies show there exists ferromagnetically coupled interactions within the [Ni(mnt)2]- anion chain (J = 42.2 cm-1), and antiferromagnetically coupled interactions between [Ni(mnt)2]- anion chains (Jeff = -4.78cm-1). The temperature dependences of the ac susceptibility revealed that this 1-D chain system is ferromagnetically ordered around 2 K and Xac measurements performed at different magnetic fields and frequencies suggest that there may coexist a degree of spin glass behaviour at low temperature.
