A new family of 1D coordination polymers (CPs) based on 4′-hydroxi-4-biphenylcarboxylic acid (4-OHBBA) linker and lanthanide metals were obtained by hydrothermal synthesis. The compounds were fully characterized and present the general formula [Ln(4-OHBBA)3(H2O)2] (where Ln = La, Pr), crystallizing in the monoclinic P21/c space group. The CPs are formed by ?fish bone-like? chains along [010] direction. Also, the topological analysis revels a 3D supramolecular structure with a 7-nodal 3,3,3,4,4,4,4-connected network and the (6.82)2(62.8)2(63.82.10)2(63)4(65.8)2(86) point symbol. The luminescence and chemical sensing tests of the europium doped compound was performed, finding that the Eu, Tb and Dy -doped samples exhibited dual emissions from the 4-OHBBA ligand and the lanthanide centres.
