Özet

In this study, two heterometallic transition metal complexes with the formulas [CoK4(mu(10)-C6H5O7)(2)](n) and [CdK(mu(8)-C6H5O7)(mu-H2O)(H2O)](n) were synthesized as crystalline compounds. The structures of these crystalline metal complexes were characterized by their spectral analyses (FT-IR, FT-Raman, thermal analysis, magnetic properties, and single-crystal X-ray diffraction techniques). According to the spectral data of the new metal complexes obtained, both metal complexes are in the monoclinic crystal system and in the P2(1)/c and P2(1) space groups, respectively. The asymmetric unit of the metal complex [CoK4(mu(10)-C6H5O7)(2)](n) contains one Co(II) ion, two potassium cations, and one (C6H5O7) citrate ligand, whereas that of the asymmetric unit of the metal complex [CdK(mu(8)-C6H5O7)(mu-H2O)(H2O)](n) contains one Cd(II) ion, one potassium cation, one (C6H5O7) citrate ligand, and two coordinated water molecules.
