  摘要：

  Two new ion-pair complexes [1-(4'-nitrobenzyl)-4-aminopyridinium]-bis(maleonitriledithiolato)nickel ([NO(2)BzPyNH(2)][Ni(mnt)(2)]) (1) and [1-(4-nitrobenzyl)-4-aminopyridinium]-bis(maleonitriledithiolato)platinum ([NO(2)BzPyNH(2)][Pt(mnt)(2)]) (2) have been prepared and characterized by elemental analyses, IR, electronic and MS spectra, single crystal X-ray diffraction and magnetic susceptibility. 1 and 2 crystallize in the monoclinic space group P2(1)/c, a = 12.331(3) angstrom, b = 26.937(6) angstrom, c = 7.322(2) angstrom, V 2349.0(10) angstrom(3), Z = 4 for 1, and a = 10.600(3) angstrom, b = 8.376(2) angstrom, c = 27.089(7) angstrom, V = 2 3 62.2(11) angstrom(3), Z = 4 for 2. The Ni(III) ions of 1 form a 1D zigzag chain within a Ni(mnt)(2)(-) column, while 2 is a dimer. Magnetic susceptibility and DSC measurements for 1 in the temperature range 2.0-300 K show the occurrence of an unusual magnetic phase transition around 160 K, and an antiferromagnetic interaction in the high-temperature phase (HT) and a spin gap in the low-temperature phase (LT), while 2 is diamagnetic.
