Abstract: Two novel ion-pair complexes: [Ln(DMA) 4(H₂O)₃][Cr(CN)₆] 2H₂O (Ln = Sm, Gd; DMA = dimethylacetamide) have been synthesized. X-Ray crystal diffraction analyses reveal that these two complexes form hydrogen-bonded structure through CN group and H₂O molecules. Variable temperature susceptibility for the GdCr complex indicates the weak antiferromagnetic interactions between cation and anion pairs through a hydrogen-bonded network.
