A novel 3D heterometallic coordination complex with (3,4,5)-connected net topology: Synthesis, structure and luminescent property

• A new heterometallic complex with 1,3,5-benzenetricarboxyl acid has been synthesized.
• The structure of the complex is determined by X-ray study.
• The complex shows a 3D structure with (3,4,5)-connected net topology.
• The coordination polymer is characterized by FT-IR, luminescence and TGA techniques.

A novel three-dimensional Ag(I)–Pb(II) heteronuclear coordination polymer, namely [Ag2Pb2(BTC)2(H2O)2]n (1), where H3BTC = 1,3,5-benzenetricarboxyl acid, has been hydrothermally synthesized and structurally characterized by elemental analysis(EA), infrared spectroscopy(IR) and single crystal X-ray diffraction. The BTC3− ligand exhibits an interesting coordination mode to form a three-dimensional (3D) framework with a novel hexa-nodal (3,4,5)-connected net topology. The thermal stability and solid state fluorescence of 1 have also been investigated.
