摘要
A new Zn（II） phosphonate complex, [Zn3（PhPO3）2（PhPO3H）2（Phen）2]n （Phen = 1,10-phenanthroline）, has been synthesized and structurally determined by X-ray single-crystal diffraction. The complex crystallizes in the monoclinic system, space group C2/c with a = 14.997（3）, b = 18.108（4）, c = 17.237（3） A, β = 96.61（3）°, V = 4649.9（16） A3, Z = 4, C48H38N4O12P4Zn3, Mr = 1182.87, Dc = 1.690 g/cm3^,μ = 1.743 mm^-1, F（000） = 2400, the final R = 0.0363 and wR = 0.0963. In the structure, the connectivity between two 5-coordinated Zn（II） atoms and four phosphonates as well as two Phen ligands form a Zn2（PhPO3H）2（PhPO3）2（Phen）2 unit, and such a neighboring unit is bridged by 4-coordinated Zn（II） to give rise to a 1D chain along the c axis. The π-π stacking interactions between Phen rings assemble adjacent chains packed together to form a 3D supermolecular architecture.
