| Abstract: A coordination polymer, namely [Fe(DPPZ)(dipic)]n (1) (DPPZ=dipyrido[3,2-a∶2′,3′-c]phenazine and H2dipic=pyridine-2,6-dicarboxylic acid), has been obtained by using hydrothermal synthesis method. The crystal structure was determined by X-ray single crystal structure analysis with the following data: Monoclinic, P21/c, a=0.794 95(16) nm, b=3.601 1(7) nm, c=0.734 32(15) nm, β=106.07(3)°, V=2.020 0(7) nm3, Z=4, Mr=503.25, Dc=1.655 g·cm-3, F(000)=1 024, μ(Mo Kα)=0.795 mm-1, R=0.038 5 and wR=0.081 0. Complex 1 has octahedral coordination geometry and forms 1D zigzag coordination chains that organize into an unusual 3D supramolecular motif through noncovalent bonds, such as π-π stacking interactions and C-H…O hydrogen bonds. The result of TG analysis indicates that the title complex is stable till 290 ℃. CCDC: 716602. |
