| Popis: | Three novel metal-organic coordination polymers based on sulfur-containing thieno[3,2-b]thiophene-2,5-dicarboxylic (trans-H2ttdc) and thieno[2,3-b]thiophene-2,5-dicarboxylic (cis-H2ttdc) acids are obtained: [Ce2(DMF)4(trans-ttdc)3]·2DMF (1), [Dy2(DMF)4(trans-ttdc)3]·4DMF (2), and [Tb2(DMF)4(cis-ttdc)3]·2.5DMF (3). Structures of the products are determined by single crystal X-ray diffraction. The compositions and nature of compounds 2 and 3 are confirmed by IR spectroscopy, elemental and thermogravimetric analyses. All three compounds are based on binuclear {Ln2(DMF)4(RCOO)6} units organized into 3D frameworks with primitive cubic topology pcu by linear organic linkers. The specific void volume in the structures of 1-3 ranges from 29% to 37%. |
