Four new coordination polymers (CPs) were obtained under hydrothermal reaction conditions using 2,4,6-pyridinetricarboxylic acid (H3PTC) and Bi(NO3)3·5H2O. The systematic high-throughput investigation of the system Bi3+/H3PTC/NaOH/HNO3/H2O led to the compounds [Bi(PTC)(H2O)2] (1), (H3O)[Bi2(PTC)(HPTC)2(H2O)2] (2), α-[Bi(PTC)] (3) and β-[Bi(PTC)] (4), which were structurally characterised by single-crystal X-ray diffraction. Compounds 1 and 2 crystallise in 2D layered structures, whereas 3 and 4 form 3D coordination networks. Employing the nomenclature proposed by Cheetham et al. 1 and 2 are classified as I1O1 (mixed inorganic–organic layers), 3 as I0O3 (3D coordination polymers) and 4 as I1O2 (mixed inorganic–organic 3D framework). In all cases the nitrogen atom of the linker is coordinated to the Bi3+ ion, which therefore acts as a tridentate pincer-type ligand. All title compounds were obtained as phase-pure products employing conventional or microwave-assisted heating, but the reproducibility of the synthesis depends on reactor size and material. In addition, the luminescence properties of 1 and 2 were studied resulting in a yellow and blue–green luminescence under UV light with emission maxima at 570 nm (λex = 343 nm) and 483 nm (λex = 347 nm) for 1 and 2, respectively. The differences in the spectroscopic properties could be assigned to the distinct coordination and chemical environments of the Bi3+ ions within these compounds.
