The structures of two new coordination polymers, namely, hydroxyl ammonium glutaratouranylate NH3OH[UO2(C5H6O4)(C5H7O4)] · H2O (I) and diethyl ammonium glutaratouranylate NH2(C2H5)2[UO2(C5H6O4) (C5H7O4)] · 2H2O (II), have been characterized by single-crystal X-ray diffraction. It has been established that the structures of complexes I and II contain [UO2(C5H6O4)(C5H7O4)]–infinite chains with the crystallochemical formula AQ02B01 ( $$\rm{A = UO_2^{2+}}, Q^{02} = C_5H_6O_4^{2-}, B^{01} = C_5H_7O_4^{-}$$ A = U O 2 2 + , Q 02 = C 5 H 6 O 4 2 − , B 01 = C 5 H 7 O 4 − ). Despite the identical compositions, uranyl glutarate chains in the studied structures appreciably differ from each other by their geometry and linking. The specific features of nonbonded interactions in the structures of complexes I and II have been characterized by the Voronoi–Dirichlet method of molecular polyhedra.
