title: Stereochemistry of new nitrogen containing heterocyclic compound XII. Polymeric uranyl complexes of hydrazone compounds.
abstract: Several dioxouranium(VI) heterochelates with tetradentate monobasic hydrazone compounds (HL(n)) have been synthesized. The heterochelates of the type [(UO2)2(HL(n))(L(n))2(OAc)2(OH2)2]n have been characterized on the basis of elemental analyses, IR and electronic spectra, conductance and magnetic susceptibility measurements. The complexes are polymeric, non-electrolytes, diamagnetic and eight-coordinated. Wilson, G.F. matrix method, Badger's formula, Jones and El-Sonbati equations were used to determine the stretching and interaction force constants from which the U-O bond distances were calculated. The bond distances of these complexes were also investigated.
