Abstract

The molecular structure of $[UO_2(o-OC_6H_4-CH=N(CH_2)_2NH(CH_2)_2N(CH_3)_2)NO_3].CH_2C1_2$ has been determined from three-dimensional X-ray data collected by counter methods. The conventional R factor obtained from least-squares refinement of atomic parameters for 1264 “observed” unique reflections is 0.082. The crystal consists of discrete monomeric molecules interspersed with solvent molecules which do not interact with the “inner core” of the complex. The coordination around uranium is approximately pentagonal bipyramidal with uranyl oxygens in axial positions; four equatorial sites are occupied by the tetradentate Schiff base, nitrate group occupying the fifth site. The bond distances and angles reveal no surprises when compared with other analogous uranyl Schiff bases complexes.
