摘要：

Two new molecular solids, [1-(2'-Cl-4'-Rbenzyl)pyridinium][bis(maleonitriledithiolato)nickel] [abbreviated as ([ClRBzPy][Ni(mnt)2]), R = Br(1), I(2)], have been prepared and characterized. The Ni(III) ions form a 1-D zigzag alternating chain within a [image omitted] column through Ni S, S S, or stacking interactions in 1 and a tetramer in 2. The variable temperature magnetic susceptibilities of 1 and 2 in the temperature range 1.8-300 K have been interpreted in terms of a simple dimer model approximation (H = -2JSASB), revealing strong antiferromagnetic interactions with the fitting value g = 1.98 and J = -231.5 cm-1 for 1, g = 1.96 and J = -245.3 cm-1 for 2.
