(a) Monodentate UO 2 (OH 2 ) 4 (O 2 P(OCH 2 C 4 H 6 OOH) 2 )+•23(H 2 O) (=UO 2 OrgPO 4 ) converts to (b) a bidentate configuration during energy minimizations from three separate monodentate starting configurations. (c) A protonated phosphoryl group allows a stable monodentate configuration to be found consistent with the EXAFS data of [47]showing monodentate phosphoryl bonding to U on bacterial surfaces at low pH.
