More Information
Summary:A 3 d -3 d heterometallic coordination polymer, M(Bpp)(BDC) ( I ) (M = Co and Zn, Bpp = 1,3- bis (4-pyridyl)propane and H 2 BDC = 1,4-benzenedicarboxylic acid), has been prepared by hydrothermal synthesis and structurally characterized by IR, elemental analysis, and single-crystal X-ray diffraction. The Co(II) and Zn(II) ions in I are located indisorder with a molar ratio of 0.35: 0.65. Complex I crystallizes in the orthorhombic space group Pbca and displays a two-dimensional 2-fold interpenetrated structure with (4,4) topology. The coexistence of two metal ions in the structure makes them more thermally stable than thepreviously reported homometallic polymers of Co(II) or Zn(II) ions. Complex I exhibits weaker antiferromagnetism than the pure Co(II) complex owing to the incorporation of Zn(II).
