| Abstract: | Four ion-pair compounds that are based on the [Pd(mnt)2]− anion were synthesized and structurally characterized. Crystal structure determinations revealed that, in all four cases, the anions and cations stack as segregated columns, and that adjacent [Pd(mnt)2]− anions exhibit a strong tendency of dimerization within an anionic column. Values of χm(T) in 2–350 K indicated that these compounds are nearly diamagnetic. Results of the spin dimer analyses for the magnetic exchange interactions between the nearest-neighbor spins qualitatively illustrated the magnetic behaviors of these compounds. |
