摘要：A three-dimensional microporous coordination polymer with weakly coordinating solvate molecules. Co-2(H2O)(4)(2,6-NDC)(2)(DME)(2)center dot 2H(2)O, 1, have been synthesized. The metal-organic framework 1 can undergo a structural transformation when the solvent molecules are removed, which is followed by the modulation of physical properties. This crystal-to-crystal transformation is reversible, and associated with a significant magnetic-susceptibility change: dropping the Curie constant from 5.947 cm(3) K to 5.535 cm(3) K and elevating the Weiss temperature from -65.3 K to -7.5 K when the solvent molecules are removed. The absorption properties of the desolvated 1 were studied for N-2 and Ar, and some preference were found most probably due to the small pore sizes in the material. (C) 2011 Elsevier Inc.
