主 题:metal-organic framework crystal structure luminescent property
摘 要:A new complex, [Zn2(HL)2(2,5-OH-pbda)]n(1, L = 1-(1 H-imidazol-4-yl)-4-(4 Htetrazol-5-yl)benzene(H2L) and 2,5-OH-H2 pbda = 2,5-dihydroxy-terephthalic acid), has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in monoclinic, space group P21/n with a = 8.8101(10), b = 17.105(2), c = 9.4014(11)A, β = 105.704(2)o, V = 1363.9(3) A3, Z = 4, C(14)H9N6O3Zn, Mr = 374.64, Dc = 1.824 g/cm3, μ = 1.831 mm^(-1), S = 1.042, F(000) = 756, the final R = 0.0309 and w R = 0.1003 for 3130 observed reflections(I 2σ(I)). The H2L ligand was deprotonated to be an HL-anion, and coordinated with Zn^(2+) to form two-dimensional(2D) Zn2(HL^-)2^(2+) sheets, which were pillared by the 2,5-OH-pbda2-ligands to form a three-dimensional(3D) dmc net with Point(Schlafli) symbol of(4·82)(4·85). The large vacancy of the dmc net is filled via mutual interpenetration of another independent framework, leading to the formation of a 2-fold interpenetrating architecture. Solid state luminescent property of 1 has been investigated.
