Two new Zn(II) coordination compounds, namely [Zn2(mbdc)2(bix)2]n (1) and [Zn4(bptc)2(bix)4]n (2) (H2mbdc = isophthalic acid, H4bptc = biphenyl-3,3′,5,5′-tetracarboxylic acid, bix = bis(imidazol-1-ylmethyl)benzene) were successfully obtained using the dual-ligand synthetic strategy. Single crystal X-ray diffraction analyses revealed that compound 1 features a 2-fold interpenetrated 3D dia-type framework, and compound 2 features a trinodal 4-connected 3D topological network. The structural variation was achieved via tuning the organic carboxylate ligand. Moreover, the luminescent properties of compounds 1 and 2 were also investigated in the solid state at room temperature.
