A novel 3D (4, 8)-connected metal-organic framework of scu topology with two types of 1D channel constructed by methylenediisophthalic acid (H4MDIP)

A novel coordination polymer 1 {[Zn5(MDIP)2(H2O)6(μ3-OH)2]·2H2O}n has been synthesized using methylenediisophthalic acid (H4MDIP) under hydrothermal conditions. Single-crystal X-ray diffraction analysis indicates that 1 shows a 3D porous framework with two types of 1D channel. The structure is further simplified by topology analysis which indicates a (4, 8)-connected net with a Schläfli symbol of (44.62)2(416.612) topology. Moreover, compound 1 displays a strong blue photoluminescent property.
