摘要

A new metal-organic coordination polymer [Zn(hfipbb)(e-urea)]n(1,H2hfipbb = 4,4'-(hexafluoroisopropylidene)bis(benzoic acid),e-urea = ethylene urea) has been urothermally synthesized and characterized by elemental analysis and single-crystal X-ray diffraction.The title complex crystallizes in monoclinic,space group P21/c with a = 13.302(4),b = 10.981(3),c = 13.804(4) ,β = 93.587(5)°,V = 2012.3(10) 3,C20H14N2O5F6Zn,Mr = 541.72,Z = 4,Dc = 0.447 g/cm3, = 0.328 mm-1,F(000) = 272,R = 0.0340 and wR = 0.1107 for 4528 observed reflections(I 〉2σ(I)).In the structure of compound 1,two Zn(Ⅱ) ions are bridged by two carboxylate groups from two hfipbb ligands to form a dinuclear unit,and each dinuclear Zn(Ⅱ) unit is linked with its two adjacent dinuclear units through four hfipbb ligands into an infinite one-dimensional double-chain.The interesting structural feature of compound 1 is that the one-D double-chains are self-interconnected into a three-D supramolecular structure through hydrogen bonds between the coordinated e-urea molecules and carboxylate oxygen atoms(N1 and O2,N2 and O4).
