Synthesis and Crystal Structure of Coordination Polymers [Zn(phen)(H_2O)_3SO_4]·H_2O

The title complex was synthesized by reaction of o-phenanthroline(phen) and zinc sulfate heptahydrate in water-ethanol solution.The crystal structure was characterized by X-ray diffraction,the complex composition was determined by elemental analysis,IR and UV spectrum.The results show that the title complex belongs to triclinic system with space group P1-and cell parameter: a=0.8042(3) nm,b=0.8636(8) nm,c=1.1595(1) nm,α=92.067(0)°,β=92.126(0)°,γ=103.761(0) °,V=0.7809(0) nm3,Z=2,Dc=1.016 g/cm3,μ=0.876 mm-1,F(000)=424.The Zn(Ⅱ) is coordinated by one phen,three water molecule and one SO2-4.The complex exhibites a distorted octahedron geommetry.3D supramolecular structure is constructed by hydrogen bonds.
