Structure of Trimethylbenzylammonium and Triethylbenzylammonium Tetrachlorouranilates

Synthesis, IR spectroscopic and X-ray structural studies of new chlorine-containing uranyl complexes (C 10 H 16 N) 2 [UO 2 Cl 4 ] ( I ) and (C 13 H 22 N) 2 [UO 2 Cl 4 ] 0.5 [UO 2 (NO 3 ) 2 Cl 2 ] 0.5 ( II) have been carried out. Uranium-containing groups in structures I and II are [UO 2 Cl 4 ] 2– complexes belonging to the crystal chemical group AM 1 4 (A = UO 2 2+ , M 1 = Cl – ),, which in II coexist with mononuclear complexes [UO 2 (NO 3 ) 2 Cl 2 ] 2– , which have a crystal chemical formula AB 01 2 M 1 2 (A = UO 2 2+ , B 01 = NO 3 – , M 1 = Cl – ). The features of intermolecular interactions in the structures of crystals I and II are considered with the help of molecular Voronoi–Dirichlet polyhedra.
