摘要:
Two lanthanide-organic frameworks Pr-2[(NIPH)(3)center dot 3H(2)O] H2O (1) and [Nd-2(NIPH)(3)center dot 3H2O]H2O (2) were synthesized via the self-assembly of Ln(NO3)center dot 6H(2)O (Ln = Pr or Nd) with 5-nitroisophthalic acid (H2NIPH) in the presence of imidazole under hydrothermal reactions. X-ray single-crystal diffraction analyses reveal that 1 and 2 are isomorphic and both exhibit an unprecedented 2D topological net. Compounds 1 and 2 both have a 3D supramolecular framework extended by hydrogen-bonding interactions between the adjacent layers. Furthermore. the magnetic behaviors for 1 and 2 in the temperature range of 2-300 K were investigated. (C) 2009 Elsevier B.V. All rights reserved
