摘要
Two 3D 4-fold interpenetrated metal-organic frameworks, [Mn(L)(bpy)]n (1) and [Cu(HL)(bpy)]n (2)(H3L = 4,4',4''-(benzene-1,3,5-triyl-tri(methyleneoxy)) tribenzoic acid, bpy = 4,4′-bipyridine), were synthesized under hydrothermal conditions, and characterized by element analyses, IR spectra, thermogravimetric analyses, X-ray powder diffraction and magnetic property studies. The single-crystal X-ray analyses revealed that 1 and 2 are homogeneous. 1 crystallizes in monoclinic, space group Cc with a = 26.794(2), b = 11.6346(10), c = 21.4614(18) ?, β = 91.570(2)°, V = 6687.9(10) A^3, Z = 8, Mr = 736.59, D = 1.463 g·cm^(-3), μ = 0.458 mm^-1c, R(int) = 0.0524, F(000) = 3040, the final R = 0.0844 and wR = 0.2266 for 8092 observed reflections(I 〉 2σ(I)). 2 crystallizes in monoclinic, space group Cc with a = 27.609(12), b = 11.126(10), c = 21.490(9) ?, β = 92.131(2)°, V = 6597(5) A^3, Z = 8, Mr = 746.21, Dc = 1503 g·cm^(-3), μ = 0.726 mm^-1, R(int) = 0.0542, F(000) = 3080, the final R =0.0681 and wR = 0.1831 for 6777 observed reflections(I 〉 2σ(I)). Two compounds are 3D [2+2]-type 4-fold interpenetrated frameworks with(6^3)(6^9.8) hms topology. The magnetic study of compound 2 shows the presence of weak antiferromagnetic interaction between the Cu^Ⅱ ions in 2.
