| الوصف: | Two new nanoscale cobalt(II) coordination compounds, (adH)3[Co(Hpzdc)(pzdc)2].6H2O (1) and [Co(pzdc)2(H2O)2]n (2) (where H2pzdc is 2,3-pyrazinedicarboxylic acid and ad is adenine), were synthesized using a sonochemical process and characterized via scanning electron microscopy (SEM), X-ray powder diffraction (XRPD) and FT-IR spectroscopy. The structural characterization of 1 through single crystal X-ray diffraction revealed that it consists of a 0D coordination compound in which Co(II) ion is six-coordinated by two pzdc2- and one pzdcH- ligands. Compound 2 however, is a 1D coordination polymer (CP) and was found to be a perfect precursor for Co3O4 nanoparticles. Changes in the morphology and size of the nanoparticles have been induced by altering the calcination temperature in the range of 400 to 850 °C. Furthermore, the magnetic behavior of 2 was studied and compared with its single crystal counterpart. |
