Polymer Complexes.LVII. Structures of Supramolecular Assemblies of Polymer Complexes of Dioxouranium(VI) with some Substituted Allyl Azodyes (Dept.P)

Abstract

Novel five polymeric dioxouranium(VI) of bidentate allyl azo homopolymer compounds derived from allyl rhodanine were prepared for the first time. The infrared spectra of the samples were recorded and their fundamental vibrational wave number was obtained. The resulting polymeric uranyl complexes have been characterized on the basis of elemental analyses, conductance and spectral (IR, NMR, and electronic spectra) data. The nature of bonding has been further discussed based on IR spectral data. The theoretical aspects are described in terms of the well-known theory of 5d-4f transitions. The coordination geometries and electronic structures are determined from a framework for the modeling of novel polymer complexes. The values of us of the prepared polymer complexes containing UO22+ were successfully used to calculate the force constant, Fuo (In mdyn/A) and the bond length Ruo (in Ao) of the U-O bond. Wilson's, matrix method, formula, and and equations were used to calculate the U-O bond distances from the values of the stretching and interaction force constants. The most probable correlation between U-O force constant to U-O bond distance were satisfactorily discussed in term of Badger's rule, Jones and El-Sonbati equations. The Hammett constant is also discussed.
