Popis:	Crystal structures of acetylurea (AcUr) complexes with middle rare-earth bromides, [Ln(AcUr)2(H2O)5]Br3·H2O (Ln = Gd, Tb), [Ln(AcUr)2(H2O)4.5][Ln(AcUr)2(H2O)4]Br6·2H2O (Ln = Dy, Ho) and [Er(AcUr)2(H2O)4]Br3, were studied by X-ray diffraction. Complex cations contain two bidentate AcUr molecules and five (Gd and Tb) or four (Er) inner-sphere water molecules; coordination numbers 9 or 8, respectively. Compounds of Dy and Ho contain two types of complex cations with coordination numbers 9 and 8.
