The First One‐Dimensional Molecular Material Featuring Maleonitriledithiolate as a Subunit Exhibiting Metamagnetic‐Like Behavior

Abstract

Abstract An ion‐pair complex [FBzPyNH 2 ][Ni(mnt) 2 ] {[FBzPyNH 2 ] + = [1‐(4′‐fluorobenzyl)‐4‐amino]pyridinium and mnt 2− = maleonitriledithiolate} has been obtained by I 2 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. KGaA, 69451 Weinheim, Germany, 2003)
