A new 3D framework compound 1 Zn(DNBPDC)2(BPY) (DBDBC =2,2′-dinitro-[1,1′-biphenyl]-4,4′-dicarboxylic acid, BPY = 4,4′-Bipyridine) with a dinuclear zinc (II) clusters as SBU have been synthesized and structurally characterized. This compound crystallizes in Tetragonal, space group I41/acd, with a = 21.2959(10)Å, b = 21.2959(10) Å, c = 27.969(3) Å, α = 90.00°, β = 90.00 (10)°, γ = 90.00°, V =12684.4(16) ų, Z = 16, Dc = 1.424 mg/cm³, μ = 0.806 mm⁻¹, F(000) = 3792. From the thermogravimetric analysis, the compound can be stabilized up to 380 °C and the skeleton collapsed occurred in about 350–550 °C. The luminescence property test shows that the compound exhibit strong emission at 485 nm. The nitrogen adsorption capacity was 10 cc/g when the compound was activated under the temperature of 77 K and reach to atmospheric pressure.
