Syntheses, Structures, and Photoluminescent Properties of Two 2D Coordination Polymers Based on 1,3-Di(2,4-dicarboxyphenyl) Benzene and 1,3-Di(4-pyridyl)propane
摘要:
Two new 2D coordination polymers, [Zn(HL)(Hbpp)]n (1) and [Cd(HL)(Hbpp)(H2O)]n (2) (H4L=1,3-di(2,4-dicarboxyphenyl) benzene, bpp=1,3-di(4-pyridyl)propane), have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analysis, elemental analysis, TGA and IR spectroscopy. Complex 1 crystallizes in monoclinic, space group P21/n, with a=13.1031(6), b=14.7315(7), c=15.0041(7)Å, β=91.202(1)°, V=2895.6(2)Å3, Dc=1.532 g/cm3, Mr=667.97, F(000)=1376.0, μ=0.909 mm-1, Z=4, the final R=0.0481 and wR=0.1304 for 7027 observed reflections with I>2σ(I). Complex 2 also belongs to the monoclinic space group P21/n, with a=13.6326(4), b=14.6432(4), c=14.9395(5)Å, β=93.132(1)°, V=2977.84(16)Å3, Dc=1.613 g/cm3, Mr=1445.98, F(000)=733.0, μ=0.794 mm-1, Z=2, the final R=0.0283 and wR=0.0784 for 7230 observed reflections with I>2σ(I). Both complexes 1 and 2 form 2D net structures, which are further linked to form 3D supramolecular net structures via intermolecular hydrogen bonds and aromatic π-π stacking interactions.
