New Monoiodoacetate Complexes of Uranyl: Synthesis and Structure
Synthesis, IR spectroscopic, and X-ray diffraction study of crystals of two new iodoacetate complexes of uranyl: [UO 2 (mia) 2 (H 2 O) 2 ] 2 ·2(C 3 H 6 N 2 O) ( I ) and (CN 3 H 6 ) 2 [UO 2 (mia) 3 ] 2 ·(C 2 N 4 H 4 ) ( II ) were performed, where mia is the CH 2 ICOO – iodoacetate ion, C 3 H 6 N 2 O...
