The literature is most prolific on neutral An amides, but neutral U and amides are also well documented. There are only few publications on amides,one being on three alkali metal amidouranate(VI)s. ° There is a paper on a compound (18) which couid be classified as of U° and two on mixed valence U /U amides (see Section 5.4 for these types). There are a number of articles on monocationic amidol/ tetraphenylborates, three on dicationic analogues, three on a cationic U salt and four on alkali metal amidoactinate(IV)s and three on corresponding U salts. For crystalline uranium amides containing only monodentate ct-bonded ligands, metal coordination numbers of 3-7 are... [Pg.122]

In hemoglobin and myoglobin the heme serves as a carrier with oxygen-heme iron (Fe2+) interacting in a ligand-metal coordination relationship. In the cytochromes heme plays a redox role, with the iron interconverting between Fe2+ and Fe3+. [Pg.894]

An example of the H-2/C=C ligand metal coordination was reported by Siebert and co-workers <1998JOM107, 2001JOM7>, who reacted 2,3-dihydro-l/7-l,3-diborole derivatives 31a-c with dirhodium-/r-dichlorotetraethylene in tetrahydrofuran (THE) at room temperature to give the dinuclear complexes bis 7 -[l,3,4,5-tetramethyl-2-(2,4,6-trimethylbenzyl)-2,3-dihydro-l,3-diborole]- and bis[77 -(4,5-diethyl-l,2,3-trimethyl-2,3-dihydro-l,3-diborole)rhodium chloride 34a-c, respectively (Equation 3). [Pg.1232]

The extraction of in HNO3 into toluene by V,V,V, V -tetrabutylmalonamide (TBMA) indicates a 3 1 ligand/metal coordination in the extracted species. IR stretching frequencies at 1,606 cm and 1,574 cm indicate the bidentate nature of the malonamide ligand, and the absence frequencies at 746cm 1,031 cm and 1,267cm indicate that the nitrate anion is not directly coordinated to the uranyl ion. ... [Pg.300]
