| Abstract: | A new ion-paired compound [4NO2BzPy]2[Co(NCS)4] (1) ([4NO2BzPy]+ = 1-(4′-nitrobenzyl)pyridinium, NCS? = isothiocyanate) is synthesized and characterized by elemental analysis, IR and UV-Vis spectra, ESI-MS and single crystal X-ray diffraction. Compound 1 is orthorhombic, space group Pbcn, with a = 13.188(2) Å, b = 8.458(1) Å, c = 29.281(4) Å, V = 3266.2(7) Å3, D calc = 1.468 g/cm3, Z = 4, F(000) = 1476, R 1 = 0.0332. The [Co(NCS)4]2? anions form an unusual layer structure by S…N and S…Co interactions, while the [4NO2BzPy]+ cations stack into a 1D column by the p…π stacking interaction in the solid state of 1. A magnetic measurement in the range 2–300 K shows a weak antiferromagnetic exchange with θ = ?2.42 K in 1. |
