The C30H30N4O10S2U 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(1)/c with a = 14.8219(14), b = 11.6177(11), c = 20.0854(15) , beta = 104.268(9)A degrees, V = 3351.9(5) (3) 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)A degrees and the S atom showing a tetrahedral environment. The crystal packing occurs intra-inter molecular N-Ha <-O and C-Ha <-O hydrogen bonds.
