A\} novel two-dimensional coordination polymer Zn 3(PTC) 2(H 2O) 8·4H 2O was formed by \{Zn(CH 3COO) 2·\}2H 2O and 2-pyridine-1,3,5-tricarboxylate(H 3PTC) under the hydrothermal condition at 417 K and characterized by fluorescence. The crystal structure of the compound was determined by single-crystal X-ray diffraction analyses. The six-coordinated Zinc(Ⅱ) center displays an octahedral geometry . The crystal is monoclinic and space group is P2(1)/c with a=0.722 70(14) nm, b= 1.866 7(4) nm , \{c=\}1.072 6(3) nm, α=90°, β=103.198(19)°, γ=90°, V=1.408 7(6) nm 3, Z=4, D c= 2.474 Mg/m 3, M r=828.536, μ=3.099 mm -1 , F(000)=1 060, GOF=0.892, R=0.061 3, wR= 0.133 9 .
The title compound Mn 3(BTC) 2(bpy)(EG)(DMF)·(DMF)·1/3(C 2H 5OH)(BTC=1,3,5-benzenetricarboxylic acid, bpy=4,4′-bipyridine, EG=ethylene glycol, DMF=dimethylformamide) was synthesized under mild conditions and its crystal structure was determined by single crystal X-ray diffraction. The compound crystallizes in the monoclinic system and belongs to space group P2 1/n with a= 1.637 2(3) nm, b=1.481 4(3) nm, c=1.838 4(4) nm, β=113.70(3)°, V=4.082 5(14) nm 3, Z=4, D c=1.508 Mg/m 3, M r=958.85, μ=1.001 mm -1, F(000)=1 920. R 1=0.098 5, wR 2= 0.218 3. Its structure reveals that Mn(Ⅱ) centers and the carboxylate groups of BTC construct 1D O—C—O—Mn chains. Then, adjacent chains are interlinked by benzene rings of BTC to form a novel 3D architecture. It contains eight-membered rings channels that are about 0.8 nm×0.8 nm viewed along the (101) direction. In addition, it is believed that the bpy acts as both an organic ligand and a structure-directing agent in the synthesis of the title compound.
