Abstract
The compound fac-[Co(NH2CH2CH2O)3]·3H2O (I) was synthesized and its crystal structure determined. Crystal data for C6H24CoN3O6: a = 14.5236(3) Å, c = 4.9346(2) Å, V = 901.43(5) Å3, T = 90 K, space group R3, Z = 3, ρcalc = 1.620 g/cm3. In the complex, the octahedral environment of the Со(III) atom is formed by three monoethanolamine ligands using N and O atoms. The structure is disordered in such a way that the two oppositely orientated CoN3O3 octahedra are superimposed on each other at an angle.
