Özet

Two new coordination polymers, [M(sac)(2)(mu-pyz)(H(2)O)(2)]n [M=Zn(II)(1), Cd(II)(2), pyz =pyrazine, and sac =saccharinate], have been prepared and characterized by elemental analysis, FTIR spectroscopy, thermal analysis and single crystal X-ray diffraction. Both complexes are isomorphous and crystallize in the triclinic P (1) over bar space group. The metal(II) ions are octahedrally coordinated by two sac, two aqua and two pyz ligands. The sac ligands are N-coordinated, while the pyz ligands are bridges between the metal centers, leading to one-dimensional linear chains. Intra-chain M-M separations in 1 and 2 are 7.218 and 7.498 angstrom, respectively. The individual chains are linked by strong OW-H center dot center dot center dot O(sac) hydrogen bonds into two-dimensional layers, which are further assembled into three-dimensional supramolecular networks by aromatic pi(sac)center dot center dot center dot pi(sac) stackings interactions.
