Abstract
A new ion-pair complex, [BrClBzIQl][Ni(mnt)2](1) ([BrClBzIQl]+ = 1-(2′ -chloro-4′ -bromobenzyl)isoquinolinium, and mnt2− = maleonitriledithiolate) has been prepared and characterized by elemental analyses, IR, MS spectra, single crystal X-ray diffraction and magnetic susceptibility. The crystals are monoclinic space group, C c, a = 9.249(3) Å, b = 18.312(5) Å, c = 32.062(9) Å, β = 90.92(1)°, V = 5430(3) Å3, Z = 4. The Ni(III) ions of 1 form a dimer with Ni…Ni distance being 4.332 Å through short Ni…S and S…S interactions. The weak anion-cation πvπ stacking interactions, C─H…N hydrogen bonds and short Ni…N interactions further generate a 3D network structure. Magnetic susceptibility measurement in the temperature range 2–300 K shows that 1 exhibits antiferromagnetic behavior with g = 2.02, J = −373.3 cm−1.
