Add to ORKGA method of synthesis of a polynuclear cobalt(II) complex with carboxylated Boltorn H20, a hyperbranched polyol of second generation, has been suggested. The logarithm of stability constant and the composition of the complex species BH20(OC(O)CH 2CH 2COO) 12Co 12 in a 50% acetone solution have been calculated from the electronic absorption spectra: logβ = 13.7 ± 0.2 and the composition M : L = 12 : 1. The IR spectroscopy and NMR ( 13C and 1H) point to the coordination of Co(II) ions not only at the surface of the molecule but also near its core. © Pleiades Publishing, Ltd., 2012
