A Zn(II) complex with a pyridyl-and carboxylate-containing ligand: synthesis and structural characterization

The hydrothermal reaction of Zn(II) nitrate hydrate with 5-(pyridin-4-yl)isophthalic acid (H2L) yields the complex [Zn-2(L)(2)(H2O)(2)]center dot 2(H2O) (1), which has been characterized by single crystal X-ray diffraction, IR spectroscopic, elemental, and thermogravimetric analyses. Complex 1 exhibits a 3-nodal (3,6)-connected 2D net structure with (4.6(2))(2)(4(2).6(10).8(3))(6(3))(4) topology. Its luminescence property was investigated, but the results show that the coordination to the zinc atom has no significant effect on the emission of the ligand.
