Abstract
The crystal and molecular structure of ∥UO 2( o-OC 6H 4CHN(CH 2) 2NH(CH 2) 2N(CH 3) 2)NO 3∥· 2Cl 2 has been determined from 3-dimensional X-ray data collected by counter methods. The structure has been refined by least-squares techniques to a final conventional R factor of 8·2 per cent. The material crystallizes in space group Pbc2 1 of the orthorhombic system, with four molecules in a cell of dimensions a = 9·298(6), b = 20·541(9) and c = 10·925(8) A ̊ . The crystal consists of discrete monomeric molecules interspersed with CH 2Cl 2 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.
