- Аннотация: Synthesis and X-ray diffraction studies of {N(C2H5)4}[AnO2(C2H4BrCOO)3] [An = U (I), Np (II), or Pu (III)] and C2H4BrCOOH (IV), where C2H4BrCOO− is an anion of the 3-bromopropionic acid, are reported. The isostructural coordination compounds I−III contain mononuclear anionic complexes [AnO2(C2H4BrCOO)3]− belonging to the crystal chemical group AB01 3 (A = AnO22+; B01 = C2H4BrCOO−). In the crystal structure of IV, the C2H4BrCOOH molecules are hydrogen bonded into centrosymmetric dimers R2 2(8). Using the method of molecular Voronoi−Dirichlet (VD) polyhedra, the features of intermolecular interactions in crystals of I−IV are discussed in support of the results of IR and UV spectroscopy experiments. Actinide contraction in I−III manifests itself in a regular reduction of the average length of the axial and equatorial bonds in hexagonal bipyramids AnO8, in an increase in νas(AnO22+) wavenumbers, and in a simultaneous decrease in the volume and sphericity degree of VD polyhedra of An atoms in the U−Np−Pu series. The title compounds represent an interesting architecture, where 3-bromopropionate ions penetrate through the square 44 net of tetraethylammonium ions and thus bind adjacent nets via the “locking effect”.
