Two new lanthanide coordination polymers, namely [Ln_2(μ_3-OH)(pydca)-(pyba)3(H_2O)]n(Ln = Pr, 1; Eu, 2; Hpyba = 4-(4-pyridyl)benzoic acid; H2 pydca = 2,6-pyridinedicarboxylic acid), have been hydrothermally synthesized and characterized by IR spectroscopy and X-ray single-crystal diffraction. The chains of 1 and 2 are constructed by tetrametallic units of [Ln_4(OH)_2(pyba)_2], which are further linked by μ_4-k_1N, k_1O, k_2O′, k_2O″-pydca and μ_2-k_1N, k_1O, k_1O′-pyba to form 2D frameworks. Luminescence measurement reveals that compound 2 exhibits strong reddish emission at room temperature.

The chains of 1 and 2 are constructed by tetrametallic units of [Ln_4 (OH) _2], which are further linked by μ_4-k_1N, k_1O, k_2O ’, k_2O "-pydca and μ_2-k_1N, k_1O, k_1O’-pyba to form 2D frameworks.
