Abstract

Two compounds based on diiodoterephthalic and diiodoterphenyldicarboxylic acids [Ba(I2TP)(DMF)] (2) and [Y(I2TerPDC)(NO3)(H2O)(DMSO)]·DMSO (3) are prepared. The obtained single-crystal samples of 2 and 3 are studied by single crystal XRD. The performed structural analysis indicates that 2 and 3 contain halogen-halogen bonds and halogen-halogen contacts, respectively. The structure of the yttrium complex 3 is less dense than that of the barium complex 2. Also, one of the two DMSO molecules in 3 is not coordinated with the cation. The latter feature allows classifying the yttrium complex as a MOF, in contrast to the barium complex. The coordination numbers of barium and yttrium in these structures are 9 and 8, respectively, typically for these cations. The presence of iodinated ligands in MOFs can lead to the formation of halogen bonds with adsorbed molecules, thus possibly affecting the selectivity of the MOFs sorption properties.
