Crystal forms of cobalt(III) tris(2-aminoethanolate) hydrates, i.e., red cubic crystals of the composition fac-[Co(NH2CH2CH2O)3] · 5.44H2O (fac-I · 5.44H2O) and blue prismatic crystals of the composition mer-[Co(NH2CH2CH2O)3] · 3H2O (mer-I · 3H2O) were studied by the 59Co, 13C NMR and X-ray diffraction methods. It was found that mer-[Co(NH2CH2CH2O)3] · 3H2O (mer-I · 3H2O) is a new pseudopolymorphic modification of fac-[Co(NH2CH2CH2O)3] · 3H2O (fac-I · 3H2O), while fac-I · 3H2O represents a new polymorphic modification of the complex mer-[Co(NH2CH2CH2O)3] · 3H2O (mer-I · 3H2O) described previously. The comparative analysis of the spectra revealed dynamic equilibrium between these geometric isomers; the fac-isomer is stable in aqueous solutions.
