摘要A coordination polymer, namely [Fe(DPPZ) (dipic)]n (1) (DPPZ =dipyfido [3,2-a :2' ,3' -c]phenazine and H2ipic =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= 1.655g·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.
