Novel supramolecular complex {[Zn 2(phen) 2(phth) 2(H 2O) 2]·2H 2O} n (phen=phenanthroline; phth=phthalate) has been synthesized by the reaction of phen and phth with zinc(Ⅱ) salt.Elemental analysis, IR spectra and X-ray crystal structure analysis were carried out to determine the composition and crystal structure of title complex. The title complex belongs to monoclinic system with space group P2(1)/n, a=0.9643(3) nm, b=0.8976(3) nm, c=2.1410(7) nm, β=90.776(5)°, Z=4, V=1.8531(10) nm 3, D c=1.598 g/cm 3, μ=1.367 mm -1, F(000)=912, R 1=0.0409, wR 2=0.0818, and the zinc atom rendered five-coordinate in a distorted trigonal bipyramidal configuration. The complex formed 1-D helix chain bridged by phth and 2-D network structure by π-π action of neighbouring helix chain.
