Interaction of Polybenzoylthiocarbamate-Modiﬁed Hyperbranched Polyesther with Co(II) and Cu(II) Nitrates
The interaction of Co(NO3)2 and Cu(NO3)2 with hyperbranched polyether containing 7 terminal benzoylthiocarbamate groups was studied by IR-Fourier and electron absorption spectroscopy. А new polynuclear complexes of Co(II) and Cu(II) with polybenzoylthiocarbamate-modiﬁed hyperbranched polyether were synthesized. It was found that the oxygen and sulfur atoms of the peripheral benzoylthiocarbamate fragments of the macroligand participate in coordination with metal ions, the composition of the complex forms M:L=7:1 of the logarithms of the conditional stability constants was 17.30±2.77 for the cobalt(II) complex and 15.92±2.28 for the copper complex(II).
