| Abstract: The allo-bisbridge 2D coordination polymer ∞2[Ni(μ-4，4′-bpy)2/2(μ-L)4/2](HL=2-indolyl-formic acid) has been obtained by using hydrothermal synthesis, and the results of X-ray single crystal diffraction analysis show that the compound crystallizes in monoclinic system, space group C2/c (No.15) with a=2.300 2(5) nm, b=1.129 1(2) nm, c=0.974 0(2) nm, β=109.85(3)°, V=2.379 2(8) nm3, Dc=1.494 g·cm-3, Z=4, F(000)=1 104, μ=0.860 mm-1, R=0.032 2, wR=0.088 8. The crystal structure consists of the [Ni(μ-4,4′-bpy)2/2(μ-L)4/2] complex molecules, in which the Ni atom is octahedrally coordinated by two N atoms from two different 4,4′-bpy molecule ligands and four O atoms from four different L- anion ligands. TG analysis indicate that title coordination polymer possesses relatively high thermal stability. CCDC: 252833. |
