A new luminescent Zn(II) coordination polymer, namely [Zn 4 (L) 2 (μ 4 -O)(H 2 O) 2 (DMF)] n (1 H 3 L=biphenyl-3,4,5-tricarboxylic acid, DMF=N,N′-dimethyl formamide) has been synthesized by combining the H 3 L ligand with Zn(II) salts under solvothermal conditions. Single-crystal X-ray diffraction analysis reveals that 1 features μ 4 -oxygen-bridged tetrahedral {Zn 4 O} clusters as building subunits, which are further bridged by L 3− ligands into a complicated three-dimensional (3D) architecture. Topological analysis reveals that it can be reduced into a (3, 6)-connected topological network with the schläfli symbol of {4·6 2 } 2 {4 2 ·6 9 ·8 4 }. In addition, the luminescent property of 1 was also investigated in the solid state at room temperature.
