Synthesis, Structure and Luminescent Property of a New Zn(Ⅱ) Coordination Polymer Based on 1,3,5-Benzenetricarboxylate and 4,4'-Bipyridine Ligands
摘要:
A new Zn(Ⅱ) coordination polymer [Zn3(BTC)2(4,4'-bpy)(CO)2]n (1, H3BTC=1,3,5-benzenetricarboxylic acid, 4,4'-bpy=4,4'-bipyridine) has been prepared through urothermal reaction of zinc nitrate hexahydrate with 1,3,5-benzenetricarboxylic acid and 4,4'-bipyridine, and characterized by elemental analysis, IR spectroscopy, TGA and powder XRD, and its crystal structure was determined by single-crystal X-ray diffraction analysis. The title compound crystallizes in the monoclinic system, space group C2/c, with a=10.262(3), b=18.838(5), c=15.083(4)Å, β=99.203(4)°, V=2878.3(14)Å3, C30H14Zn3N2O14, Mr=822.54, Z=4, Dc=1.898 g/cm3, μ=2.561 mm-1, F(000)=1640, R=0.0363 and wR=0.0932 for 2828 observed reflections (I>2σ(I)). X-ray analysis shows that the asymmetric unit of the title compound contains two crystallographically unique Zn(Ⅱ) atoms which are connected by BTC3- ligands and 4,4'-bpy coligands to form a 3D framework with 1D channels. The solid luminescence of ligand and the title complex was also studied at room temperature.
