| 摘 要： | The hydrothermal reaction of 5-methoxyisophthalic acid(MeO-H_2ip), 1,3-bis(2-methylimidazol-1?-yl)propane(bmip) and Zn(NO_3)_2·6H_2O in the presence of NaOCH_3 gave rise to a three-dimensional(3-D) metal-organic framework containing octanuclear Zn(II) units, Zn_4(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, M_r = 334.62, D_c = 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.
