Magnetism of [Ni(dmit)2] salts with [meso- and (1S, 2S)-diphenyl-1,2-ethanediammonium]([18]crown-6)2 supramolecular cations.
Meso- and (1S, 2S)-diphenyl-1,2-ethanediammonium (DPEDA2+) complexed with [18]crown-6 were introduced into [Ni(dmit)2]-based magnetic salts as countercations. The configurational difference of DPEDA2+ modulated the crystal structure and magnetic behavior of the salts. A two-dimensional (2D) Heisenberg antiferromagnetic square lattice was observed in (meso-diphenyl-1,2-ethane diammonium2+)([18]crown-6)2[Ni(dmit)2](-)2, which was the first example of a 2D magnetic lattice in [Ni(dmit)2]- salts.
