A novel lead coordination compound based on an extend viologen derivated ligand, [Pb4(TTVTC)Cl6(H2O)2] was successfully assembled under solvothermal condition and characterized. Single crystal structure study reveals that compound 1 is a 2D layer. Adjacent Pb2+ ions are doubly bridged by isophthalates and µ 2-Cl ions to form an infinite one dimensional (1D) ladder-like chain. The chains are further interlinked by the TTV moieties to generate a 2D layer. And hydrogen bond interaction based on C–H···Cl and C–H···O forms the supramolecular 3D structure. Additionally, Solid- state fluorescence shows that 1 emits pale green fluorescence, which can be assigned to the inter-ligand π*–π and/or π*–n transitions.
