| Abstract: | New heterometallic Ge(IV) and Co(II), Ni(II), and Cu(II) complexonates based on ethylenediaminetetraacetic acid (H4Edta) were synthesized. The composition of the complexes was determined using elemental analysis and thermogravimetry. Comparison of the IR spectra of Ge(OH)(HEdta)] ? H2O, which was structurally characterized previously, with those of the new complexes provided information on the composition and structure of their inner and outer spheres. The cobalt and nickel coordination polyhedra were identified by analyzing the diffuse reflection spectra and the effective magnetic moments and that of copper was identified by EPR. |
