| Abstract: | A three-dimensional chiral polymer, Zn（H2O）（glu）]n（1）,synthesized though the solution reactions of L-glutamic acid and zinc nitrate,has been characterized by EA,IR and X-ray crystallography.X-ray crystal structure analysis reveals 1 crystallizes in the orthorhombic P212121 chiral space group,cell parameters： a = 7.144（2） A°,b = 10.355（3）A°,c = 11.065（4）A°,V = 818.6（5） A°3,Z = 4.Compound 1 is a kind of microporous polymer-material with helix chain.The helix chain is bridged by the α-carboxyl of L-glutamic acetate.The nano-pores（9.8 × 5.5 A°2） were found in the polymer,in which there are interesting guest 14-cycle water clusters. |
