摘要：

Three ion-pair Ln-Cr complexes [Sm(DMA)(4)(H2O)(3)][Cr(CN)(6)].2H(2)O, [Gd(DMA)(3)(H2O)(4)] [Cr(CN)(6)].2H(2)O and [Er(DMA)(3)(H2O)(4)][Cr(CN)(6)] (DMA=dimethylacetamide) have been synthesized. X-ray structure analyses of the title complexes revealed that there is a hydrogen-bonding network through CN groups and H2O molecules. Variable temperature magnetic susceptibilities indicate weak antiferromagnetic interactions between cation and anion pairs moderated through the hydrogen bonding network.
