New heterometallic complexes of Nd(III) and Co(II) based on ethylenediaminetetraacetic and ethylenediaminedisuccinic acids have been synthesized. The complexes studied by electron absorption spectroscopy, IR-spectroscopy, and thermogravimetric analysis. The influence of a number of factors on the pr...
