Reactions of ZnO, HCO2H, and 4,4'-bipy (molar ratio＝1∶3∶1.25) in H2O/DMF (volume ratio＝13∶1) at 60 ℃ afforded [Zn(HCO2)2(4,4'-bipy)]∞ with 75% yield. It crystallizes in the tetragonal symmetry with space group P43212 and lattice parameters: a＝b＝0.79675(5) nm, c＝1.7627(2) nm, V＝1.1190(3) nm3, Z＝4, Dc＝1.850 g/cm3, Mr＝311.60, F(000)＝632, μ＝22.07 cm－1, R1＝0.0183, and wR2＝0.0483. The X-ray analysis reveals that the zinc ion is octahedrally coordinated by two N atoms from one 4,4'-bipy ligand and four O atoms from four anions. The ZnN2O4 octahedra are connected via two bridging 4,4'-bipy ligands and four bridging anions, forming an interesting 3D scaffold structure. The thermal and photoluminescent properties of the title compound were also studied.
