Определены стехиометрия и константы соответствующих равновесий.The equilibria of complex formation between Ni(II) and glycerol in a wide range of рН have been studied by nuclear magnetic relaxation, pH-potentiometry, and mathematical modelling. The self-association of glycerol (H 3Glr) 2 and the formation of outer-sphere complexes {[Ni aq]H 3Glr} 2+ and {[Ni aq](H 3Glr) 2} 2+ as well as mono- and polynuclear glycerates [NiH 2Glr] +, [NiHGlr], [Ni 2Glr] +, [Ni(H 2Glr)(H 3Glr)] + and [Ni 4(HGlr) 3(H 2Glr)]NO 3 have been observed. The stoichiometry and equilibrium constants have been calculated.
Методами ядерной магнитной релаксации и рН-потенциометрии в сочетании с методом математического моделирования описаны равновесия комплексообразования никеля(II) с глицерином в широком диапазоне рН. Выявлена самоассоциация глицерина (H 3Glr) 2, образование внешнесферных комплексных форм {[Ni aq]H 3Glr} 2+ и {[Ni aq](H 3Glr) 2} 2+, а также моно- и полиядерных глицератов состава: [
