Abstract
A new ion-pair complex [1-(4'-cyanobenzyl)pyridinium]
[Ni(mnt)(2)] (1), in which mnt(2-) = maleonitriledithiolate,
have been fabricated and its X-ray single crystal structural
analyses at 293, 180 and 140 K shown that the [Ni(mnt)(2)](-)
anions and [CNBzPy](+) cations form a well-separated stacking
column along c-axis direction, within which [Ni(mnt)(2)](-)
anions are uniformly spaced to give a one-dimensional (I-D)
chain structure. Bulk magnetic properties of this complex have
been investigated in the temperature range of 2-400 K and shown
there exists spin kink at similar to190 K. In low temperature
region, weak ferromagnetic behavior occurs in 1. (C) 2003
