A convenient method for the preparation of complexes of the uranyl [UO 2 ] 2+ , vanadyl [VO] 2+ and [ZrO] 2+ ions with vitamin B13 (Orotic acid; H 3 OA) is reported and this has enabled three complexes of orotate anion (1À) to be formulated: 6, 3, respectively]. The new bisorotate (H 2 OA) 1À comple
