Synthesis, Spectroscopy and X-Ray Studies of [N'-(2-Hydroxy-3-Methoxybenzylidene)-4-Methylbenzenesulfonohydrazide]Uranyl(IV)

Abstract

The C<inf>30</inf>H<inf>30</inf>N<inf>4</inf>O<inf>10</inf>S<inf>2</inf>U complex (I) has been investigated and characterized by single crystal X-ray diffraction (CIF file CCDC no. 970349), IR and UV-Vis spectroscopic techniques. X-ray results show that the title compound crystallizes in the monoclinic system, space group P2<inf>1</inf>/c with a = 14.8219(14), b = 11.6177(11), c = 20.0854(15) Å, β = 104.268(9)°, V = 3351.9(5) Å3 and Z = 4. In the title structure, the U atom has a distorted pentagonal-bipyramidal geometry with a tetradentate Schiff base ligand in the equatorial plane and oxo atoms in the axial positions. The C-S-N(H)-N linkage is non-planar, the torsion angle being -98.7(15)° and the S atom showing a tetrahedral environment. The crystal packing occurs intra-inter molecular N-H⋯O and C-H⋯O hydrogen bonds. © 2014 Pleiades Publishing, Ltd.
