Synthesis, Crystal Structure and Photoluminescent Property of a 3D Hydrogen-bonded Supramolecular Compound with Large Channels

摘要

The title compound, [Pd(2,2'-bipy)2](H3adip)2·4H2O, was synthesized via the hydrothermal reaction of PdCl2 with 5-aminodiacetic isophthalic acid (H4adip) in an acetic acid water solution. It was characterized by elemental analysis and infrared spectrum. Crystal data for C44H44N6O20Pd: monoclinic, space group P21, a=11.0674(2), b = 9.9716(2), c = 20.5770(3)(A),β = 92.7300(3)°, V = 2268.29(7)(A)3, Z = 2, Mr = 1083.25, Dc = 1.586 g/cm3, F(000) =1112,μ =0.499 mm-1,λ(MoKα) = 0.71073(A), T = 293(2) K, 2θmax = 51.38°, GOOF = 1.067, R = 0.0268 and wR = 0.0710 for 3770 reflections with 1＞2σ(I). X-ray diffraction studies reveal that the title compound has an interesting 3D microporous architecture via hydrogen bonds with the cations located inside the channel.
