The First Uranyl Monoiodoacetate Complexes: Synthesis and Structure

Thecrystals of (CN3H6)(3)[UO2(mia)(3)](2)(NO3) (I) and (CN3H6)(3)[UO2 (mia)(3)](2) (OH) (II), where mia is the monoiodoacetate ion CH2ICOO-, were synthesized and studied by IR spectroscopy, thermogravimetric analysis, and X-ray diffraction. The uranyl-containing [UO2(mia)(3)](-) complexes in the structures of I and II are described by the crystal chemical formula A(B-01)(3), where A = UO22+, B-01 = mia. The non-covalent interactions in the crystals of I were analyzed by the method of molecular Voronoi-Dirichlet polyhedra. Considering the available published data, it was found that the nature of the iodine-containing carboxylate ions (aliphatic or aromatic) does not affect the geometric characteristics (d(I center dot center dot center dot O) and

Automated summary

The crystals of two complexes were synthesized and studied by various methods. The non-covalent interactions in one of the crystals were analyzed and it was found that the nature of the iodine-containing carboxylate ions does not affect the geometric characteristics.
