A new 2-D Cu(II) coordination polymer, [Cu-2(L)(H2O)(3)]4.5H(2)O (1) [H4L=5,5-(pyrazine-2,3-diylbis(azanediyl))diisophthalic acid], has been synthesized from the reaction of Cu(NO3)(2)3H(2)O with H4L under solvothermal conditions. H4L was prepared and characterized by H-1 NMR, C-13 NMR, elemental analysis (EA), and infrared spectroscopy (IR). X-ray single-crystal diffraction analysis reveals that 1 crystallized in the hexagonal space group P6(5)22 with a=16.318(1), b=16.318(1), c=35.632(6)angstrom, V=8217.0(8)angstrom(3), Z=12 and afforded 2-D grid-like double layers with a [3,5] topology network. The staggered arrangement of the 2-D layers afforded a dense structure through H-bonds. Further characterizations for 1 were performed by powder X-ray diffraction, thermogravimetric analysis, EA, IR, etc. Magnetic measurements revealed antiferromagnetic interactions between the adjacent Cu(II) centers within 1.
