Two metal organic structures composed of the ligands benzene-1,4-dicarboxylate and pyridine-2,5-dicarboxylate and bismuth cations are presented: (H2Im)[Bi(1,4-bdc)2] (1) and [Bi(pydc)(NO3)2(H2O)2]·H2O (2) (bdc = benzenedicarboxylate, H2Im = imidazole cation, pydc = pyridinedicarboxylate). Both compounds were synthesised via grinding and the crystal structure of compound (2) was solved based on its powder diffraction pattern. Compound 1 crystallised isostructurally to the dimethyl ammonium containing compound (dma)[Bi(1,4-bdc)2]. Raman spectroscopy and extended X-ray absorption fine structure (EXAFS) measurements provided additional information about the two mechanochemically synthesised metal organic compounds.
