新型离子对配合物[BrBzMeQl][Ni(mnt)2] (1) ([BrBzMeQl]+ = 1-（4′-溴苯基）-2-甲基喹啉；Mnt2−=马来腈二硫代酸盐)，并对其进行了表征。x射线衍射分析表明，Ni(mnt)2阴离子与1的[BrBzMeQl]+阳离子形成完全分离的堆叠柱，Ni···Ni距离在3.717 ~ 4.466 Å之间交替。在75 ~ 300 K范围内测量了1的变温磁化率，结果表明该配合物具有反铁磁性。
A new ion-pair complex, [BrBzMeQl][Ni(mnt)2] (1) ([BrBzMeQl]+ = 1-(4′-bromobenzyl)-2-methylquinolinium; mnt2− = maleonitriledithiolate), has been prepared and characterized. X-ray diffraction analysis shows that the Ni(mnt)2 anion and [BrBzMeQl]+ cations of 1 form completely segregated stacking columns, with the Ni ··· Ni distances alternating between 3.717 and 4.466 Å in the Ni(mnt)2 stacking column. The variable-temperature magnetic susceptibilities of 1 have been measured over the range 75–300 K and the results reveal that the complex exhibits antiferromagnetic behavior.
