Resumo
The preparation, characterization and spectroscopy of complexes of uranyl nitrate with the lactams: d-valerolactam (d-val, C H NO), 5 9
´-caprolactam (´-capro, C H NO), 2-azacyclononanone (2-aza, C H NO) and 2-azacyclotridecanone (2-actd, C H NO) are 6 11 8 15 12 23
described. They were prepared by reaction of hydrated uranyl nitrate with the ligands in ethanolic solution (molar ratio 1:2) and presented
the general composition UO (NO ) .2L, except for the ´-capro complex that is dimeric, with composition: (UO ) (NO ) (O )(´-capro) . 2 32 22 32 2 4
The peroxo bridge was introduced when 2,2-dimethoxypropane contaminated with peroxide was used to precipitate the crystals. They
were characterized by CHN microanalyses, IR spectra, TG and DSC analyses and emission spectra in the visible region. The structure of
the ´-capro complex was determined by X-ray single crystal analysis.
