TLDR
An ion-pair complex [FBzPyNH2][Ni(mnt)2] has been obtained by I2 oxidation of the corresponding dianion complex, and exhibits antiferromagnetic ordering below 2.5 K.Abstract:
An ion-pair complex [FBzPyNH2][Ni(mnt)2] {[FBzPyNH2]+ = [1-(4′-fluorobenzyl)-4-amino]pyridinium and mnt2− = maleonitriledithiolate} has been obtained by I2 oxidation of the corresponding dianion complex. It forms a wellsegregated stacking column structure in the solid state, and exhibits antiferromagnetic ordering below 2.5 K. It is the first complex in this series of complexes containing a maleonitriledithiolate dianion that exhibits metamagnetism. (© Wiley-VCH Verlag GmbH & Co.
