A Cu(Ⅱ) Coordination Polymer with 5-Tert-butyl Isophthalate Linker: Synthesis, Crystal Structure, and Magnetic Properties

摘要

A new Cu(Ⅱ) metal-organic coordination polymer,{[Cu2(tbip)2(bie)2]-H2O}n(1,H2 tbip = 5-tert-butyl isophthalic acid,bie = l,2-bis(imidazol-l'-yl)ethane),was assembled under hydrothermal conditions by the reactions of Cu(Ⅱ) acetate with H2 tbip and bie.Complex 1 was characterized by elemental analysis,IR spectroscopy and X-ray single-crystal diffraction.Complex1 crystallizes in triclinic,space group PI,with α = 9.9145(10),b = 13.2211(13),c = 15.4363(15) nm,α = 87.0250(10),β = 88.3220(10),γ = 83.8240(10)°,V= 2008.4(3) nm3,Z = 2,Dc = 1.505 Mg/m3,F(000) = 944,μ = 1.125 mm-1,S = 1.030,the final R = 0.0336 and wR = 0.0790.The results reveal that complex 1 is a two-dimensional layered structure.In addition,magnetic properties of 1 were also investigated.
