Özet

The hydrothermal reactions of some metal ions with 2,2'-dimethylglutaric acid (22dmgH(2)) and 1,2-bis(imidazol-1-ylmethyl)benzene (obix) newly afford four coordination polymers are called, {[Co-2 (mu-22dmg)(2)(mu-obix)(2)]center dot 1.5H(2)O}(n) (1), {[Cu(mu-22dmg)(mu-obix)]center dot H2O}(n) (2), {[Zn-2(mu-22dmg)(2)(mu-obix)(2)]center dot 2H(2)O}(n) (3) and [Cd-2(mu-22dmg)(2)(mu-obix)(2)(H2O)](n) (4). All of the complexes were characterized by elemental analysis, IR spectra, single crystal X- ray diffraction, powder X-ray diffraction (PXRD), and thermal analysis techniques. Furthermore, photoluminescence and topological properties were studied. The X-ray single crystal study shows that complexes 1, 3 and 4 display 3-fold parallel interpenetrating networks with hcb topology showing an unusual 2D + 2D + 2D -> 2D structures. Topological analysis reveals that complex 2 has an uninodal 4-c net sql topology with the point symbol of 4(4).6(2). Atomically-detailed simulations were finally performed to compute hydrogen (H-2) uptake in these complexes at 77 K.
