A novel coordination polymer,{Zn[(BTDC)_2(DMF)_2]}_4·(DMF)_4(1),was synthesized by solvothermal reactions of 2,2′-bithiophene-5,5′-dicarboxylic acid(H_2BTDC) and Zinc nitrate.The structure was characerized by X-ray single-crystal diffraction and elemental analysis.1 belongs to monoclinic system,space group P2(1)/c with a=6.5913(13)(A),b=22.813(5)(A),c=16.315(3)(A),V=2 450.5(9)(A)~3,Z=4,F(000)=1 112,ρ_(calcd)=1.455 g·cm~(-3),R_1=0.040 2,wR_2=0.082 4[I>2σ(I)].The crystal cell contains two ligands and two coordinated solvent molecules DMF,and one free DMF molecule coordinated with a zinc atom center.They build up a zigzag chain of 1D framework.
