A [UO(2)dapsox]3H(2)O (H(2)dapsox = 2 ' ,2 " '-(2,6-pyridindiyldiethylidine)dioxamohydrazide) has been synthesized and determined by the elemental analysis, the H-1 and C-13 NMR spectra, IC and the electronic absorption spectral as well as by thermal analysis (DSC and TG). The [UO(2)dapsox]3H(2)O complex's geometry is a pentagonal pyramid with two oxo oxygen atoms in apical positions and a planar pentadentate in the equatorial plane. This geometry (existing in spire of the solvents present within the crystal lattice) is resulting from the steric effects imposed by the coordinated acylhydrazone.
