Crystal structure and magnetic properties Gd2([18]crown-6)2(OH)2(CH3CN)2[Ni(dmit)2]4 complex having f- and π-spins

Crystal structure and magnetic properties of Gd-2([18]crown-6)(2)-(OH)(2)(CH3CN)(2)[Ni(dmit)(2)](2) (dmit(2-) = 2-thioxo-1,3-dithiole-4,5-dithiolate) are reported. Gd3+ ions (S = 7/2) were introduced into the pi-spin network of [Ni(dMit)(2)](-) (S = 1/2) complex as a binuclear supramolecular cation, Gd-2([18]crown-6)(2)(OH)(2)(CH3CN)(2), in which two Gd([18]crown-6) units are bridged with two hydroxide ions. The weak antiferromagnetic interactions between Gd...Gd through hydroxide ions were observed, and [Ni(dMit)(2)](-) formed isolated monomers and dimers in the crystal.
