The hydrothermal reaction of 5-methoxyisophthalic acid(MeO-H2ip), 1,3-bis(2-methylimidazol-1-yl)propane(bmip) and Zn(NO3)2·6H2O in the presence of NaOCH3 gave rise to a three-dimensional(3-D) metal-orga...The hydrothermal reaction of 5-methoxyisophthalic acid(MeO-H2ip), 1,3-bis(2-methylimidazol-1-yl)propane(bmip) and Zn(NO3)2·6H2O in the presence of NaOCH3 gave rise to a three-dimensional(3-D) metal-organic framework containing octanuclear Zn(II) units, [Zn4(MeO-ip)3(OH)2(bmip)]n. Single-crystal X-ray diffraction analysis reveals that the complex crystallizes in the triclinic space group P1 with a = 11.348(3), b = 14.163(4), c = 15.088(4) , α = 108.537(2), β = 106.542(2), γ = 103.106(1)o, V = 2065.4(9) -3, Z = 2, Mr = 334.62, Dc = 1.740 g·cm-(-3), μ = 2.375 mm-(-1), S = 1.015, F(000) = 1096, the final R = 0.0272 and w R = 0.0715 for 8929 observed reflections(I 〉 2σ(I)). The complex is thermally stable up to 370 oC, and exhibits photoluminescent emission at 450 nm on 350 nm excitation.展开更多
