Description

The reaction of aqueous solutions of uranyl perchlorate with selected organic amides was studied in the dark and under the sunlight. The complexes [UVIO2(C3H7NO)5](ClO4)2 (I) and [UIV(C3H8N2O)4(Н2О)4](ClO4)4 (II), where C3H7NO is N,N-dimethylformamide (Dmfa) and C3H8N2O is N,N-dimethylcarbamide (a-Dmur), were studied by X-ray diffraction. Complex II and the complex UIV(s-Dmur)4(Н2О)4(ClO4)4 (III), where s-Dmur is N,N'-dimethylcarbamide, were studied by IR spectroscopy. Crystals I and II are composed of mononuclear [UO2(Dmfa)5]2+ and [U(Dmur)4(Н2О)4]4+ groups as uranium-containing structural units belonging to the crystal-chemical groups A#041C#71 (#0410# = UVI, #041C#1 = O2– and Dmfa) and A#041C#81 (#0410# = UIV, #041C#1 = Dmur and Н2О) of uranium complexes, respectively. The mononuclear uranium- containing complexes in the crystals of U(IV) and U(VI) perchlorates were found to obey the 14 neighbors rule.
