  2D crystal structure, magnetic behavior and theoretic analysis of two new molecular solids based on Ni(maleonitriledithiolate)2 monoanion with substituted 2-aminopyridinium

  摘要：

  Two new molecular solids, [BzPyNH(2)][Ni(mnt)(2)](1) and [2-NpCH2PyNH2][Ni(mnt)(2)](2) (mnt(2) = maleonitriledithiolate, [BzPyNH(2)](+) = 1-benzyl-2-aminopyridinium and [2-NpCH2PyNH2](+) = 1-(2'-naphthylmethylene)-2-aminopyridinium) have been characterized structurally and magnetically. The Ni(I) ions of 1 and 2 form a 1D magnetic chain within a [Ni(mnt)(2)] column through Ni center dot center dot center dot N or pi center dot center dot center dot pi interactions. Some weak interactions observed in 1 and 2 give further rise to a 2D structure. The overlapping fashions of the [Ni(mnt)(2)] anions are different when the 2-aminopyridine ring was fixed and the phenyl ring changed into the naphthyl ring of the cation. Magnetic susceptibility measurements in the temperature range 2-300 K show that 1 is weak antiferromagnetic coupling, while 2 exhibits a novel and interesting spin-gap transition around 140 K with Delta/k(b) = 381.4 K.
