摘要：
Two novel ion-pair complexes: [Ln(DMA)(4)(H2O)(3)][Cr(CN)(6)]. 2H(2)O (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.
