Synthesis, structure and luminescent property of a new europium-based coordination polymer constructed from biphenyl-3,4′,5-tricarboxylic acid

• Synthesis of a europium MOF with (3, 6)-connected net topology.
• The 3D framework was proved by single-crystal X-ray diffraction.
• The luminescent property was investigated.

A new 3D lanthanide metal–organic framework Eu(BPT)(DMF)(H2O)
• (H2O)0.5] (1) has been synthesized by self-assembly of Eu(III) ions and ligand biphenyl-3, 4′, 5-tricarboxylate under solvothermal reaction conditions. X-ray crystallography reveals that 1 exhibits a (3, 6)-connected topology, with dinuclear europium clusters as 6-connected nodes and C2-symmetric ligands BPT as 3-connected nodes. In addition, the luminescence sensitization of 1 via excitation of the ligand is highly efficient.
