| 摘 要： | 1 INTRODUCTION The rational design and synthesis of metal-organic coordination polymers have generated considerable interest in supramolecular chemistry and material science owing to their intriguing structural diver- sities and potential applications as functional mate- rials1～3]. Up to now, some structural motifs with specific topologies and functions have been con- structed through rational combination of organic li- gands containing appropriate coordination sites and metal ions beari… |

| Abstract: | Three ZnII coordination polymers, Zn(py)(H2O)(dpa)]n 1, Zn2(4,4-bipy)2(dpa)2]n 2 and Zn(bpe)(H2O)2(Hdpa)2]n 3 (py = pyridine, H2dpa = diphenic acid, 4,4′-bipy = 4,4′-bipyridine, bpe = 1,2-bis(4-pyridyl)ethane), were synthesized and characterized by X-ray single-crystal structure determination. 1 crystallizes in monoclinic, space group C2/c with a = 23.014(3), b = 8.7184(13), c = 18.091(3) , β = 95.964(3)o, V = 3610.2(9) 3, Z = 8, C19H15NO5Zn, Mr = 402.69, Dc = 1.482 g/cm3, F(000) = 1648, μ(MoKα) = 1.389 mm-1, the final R = 0.0431 and wR = 0.1120 for 4239 observed reflections with I > 2((I). 2 crystallizes in orthorhombic, space group Fddd with a = 23.1613(5), b = 24.0324(6), c = 29.4785(1) , V = 16408.4(5) 3, Z = 32, C24H16N2O4Zn, Mr = 461.76, Dc = 1.495 g/cm3, F(000) = 7552, μ(MoKα) = 1.232 mm-1, the final R = 0.0542 and wR = 0.1724 for 3632 observed reflections with I > 2((I). 3 crystallizes in orthorhombic, space group C2/c with a = 19.142(4), b = 13.862(3), c = 15.625(3) , β = 122.404(3)o, V = 3500.3(11) 3, Z = 8, C20H17NO5Zn0.50, Mr = 384.03, Dc = 1.457 g/cm3, F(000) = 1592, μ(MoKα) = 0.766 mm-1, the final R = 0.0400 and wR = 0.1210 for 4024 observed reflections with I > 2((I). |
