  Two quasi-one-dimensional molecular solids based on Ni(mnt)2 anion: Crystal structures, spectra, and magnetic properties

  摘要：

  Two new molecular solids, [DiClBzPyNH(2)][Ni(mnt)(2)] (1) and [DiClBzPyN(CH3)(2)][Ni(mnt)(2)] (2) ([DiClBzPyNH(2)](+) = 1-(2',4'-dichlorobenzyl)-4-aminopyridinium, [DiClBzPyN(CH3)(2)](+) =1-(2',4'-dichlorobenzyl)-4-dimethylaminopyridinium, and mnt(2-) = maleonitriledithiolate) have been prepared and characterized by elemental analyses, IR, MS spectra, single-crystal X-ray diffraction and magnetic susceptibility. The Ni(III) ions of both 1 and 2 form a 1D zigzag Magnetic chain within a Ni(mnt)(2)(-) Column through Ni---S, S---S, Ni---Ni, or pi---pi interactions. The chain is alternating in 1 with Ni---Ni distances of 3.869 and 4.074 angstrom, while it is uniform in 2 with Ni---Ni distances of 4.159 angstrom. Magnetic Susceptibility measurements in the temperature range 1.8-300 K show that 1 exhibits antiferromagnetic behavior, while 2 shows an unusual magnetic phase transition around 140 K, and antiferromagnetic interaction in the high-temperature (HT) phase and spin gap in the low-temperature (LT) phase. The phase transition for 2 is second order by determination of DSC analyses. (c) 2006 Elsevier B.V. All rights reserved.
