  3D network structure and spin gap behavior in two new molecular magnets based on bis(maleonitriledithiolato)nickelate monoanion

  摘要：

  Two new molecular magnets, based on [Ni(mnt)(2)] monoanion, [DiBrBzPy][Ni(mnt)(2)] (1) and [DiBrBzIQl][Ni(mnt) 2] (2) ([DiBrBzPy](+) = 1-(3',5'-dibromobenzyl) pyridinium, [DiBrBzIQl](+) = 1-(3',5'-dibromobenzyl) isoquinolinium and mnt(2) = maleonitriledithiolate), were prepared and characterized by elemental analyses, IR, ESI-MS spectra, single crystal X-ray diffraction and magnetic measurements. The [Ni(mnt)(2)] anions and the cations of 1 and 2 are alternately stacked and form 1D column via pi center dot center dot center dot pi stacking interactions between the [Ni(mnt)(2)] anions and the neighboring cations. Some weak Ni center dot center dot center dot N, C center dot center dot center dot N interactions and CAH center dot center dot center dot Br, CAH center dot center dot center dot N hydrogen bonds between the adjacent columns further generate a 3D network structure. Magnetic susceptibility measurements show that both 1 and 2 exhibit the typical magnetic behavior of a spin gap system with an energy gap of 1151.9 K for 1 and 73.9 K for 2. (C) 2008 Elsevier B. V.
