abstract = "Metal-organic frameworks (MOFs) are regarded as promising materials for applications in
catalysis, separation, gas storage and molecular recognition. Here we report the synthesis and
characterization of novel silver(I) MOF obtained by the reaction of silver(I) nitrate with 1,2,4,5-
benzenetetracarboxylic acid (H4BTEC) and thiomorpholine-4-carbonitrile (tmc). As shown by
X-ray difraction analysis, silver(I) centers have distorted tetrahedral geometry with two
coordination sites occupied by carboxylic oxygen atoms of two H4BTEC, and the other two by
N-atom from nitrile group and S-atom of tmc, respectively. Adjacent silver-carboxylate chains
are connected by two tmc ligands into a 2D polymeric structure. Water molecules between these
2D layers are hydrogen bonded to carboxylic groups from adjacent layers and thus expanding
the 2D structure into a supramolecular 3D structure. Hydrogen bonds make this structure
flexible and suitable for gas absoption. Potential aplication of this coordination polymer as a
hydrogen storage material will be the subject of further investigations., Metal-organske umrežene strukture (engl. Metal organic frameworks, MOFs) predstavljaju
potencijalno dobre materijale sa primenom u katalizi, odvajanju, skladištenju gasova i
molekulskom prepoznavanju. U ovom radu opisana je sinteza i karakterizacija novog MOF-a
srebra(I) dobijenog reakcijom srebro(I)-nitrata sa 1,2,4,5-benzentetrakarboksilnom kiselinom
(H4BTEC) i tiomorfolin-4-karbonitrilom (tmc). Rendgenska strukturna analiza je pokazala da
srebro(I) centri imaju distorgovanu tetraedarsku geometriju, pri čemu dva koordinaciona mesta
zauzimaju atomi kiseonika dva molekula H4BTEC, dok su druga dva koordinacina mesta zauzimaju
redom N-atom nitrilne grupe i S-atom tmc-a. Susedni srebro-karboksilatni lanci su povezani
preko dva tmc liganda u 2D polimernu strukturu. Između 2D slojeva nalaze se molekuli vode koji
grade vodonične veze sa karboksilatnim grupama iz susednih slojeva formirajući
supramolekulsku 3D strukturu. Vodonične veze čine ovu strukturu fleksibilnom i pogodnom za
apsorpciju gasova. Potencijalna primena ovog koordinacionog polimera za skladištenje vodonika
će biti predmet daljih istraživanja.",
