Synthesis and structural studies of a bis(carbamoyl methyl) sulfoxide complex of uranyl nitrate

A new tri-functional ligand i Bu 2 NCOCH 2 SOCH 2 CON i Bu 2 was prepared and characterized. The coordination chemistry of this ligand with uranyl nitrate was studied with IR, 1 H NMR, electrospray mass-spectrometry, thermogravimetry, and elemental analysis. The structure of [UO 2 (NO 3 ) 2 ( i Bu 2...

Description
Summary:A new tri-functional ligand i Bu 2 NCOCH 2 SOCH 2 CON i Bu 2 was prepared and characterized. The coordination chemistry of this ligand with uranyl nitrate was studied with IR, 1 H NMR, electrospray mass-spectrometry, thermogravimetry, and elemental analysis. The structure of [UO 2 (NO 3 ) 2 ( i Bu 2 NCOCH 2 SOCH 2 CON i Bu 2 )] was determined by single-crystal X-ray diffraction. The uranium(VI) ion is surrounded by eight oxygens in a hexagonal bipyramidal geometry. Four oxygens from two nitrates and two oxygens from the ligand form a planar hexagon. The ligand is a bidentate chelate, bonding through sulfoxo and one of the carbamoyl groups to uranyl nitrate.
